医学论文中logistic回归分析的误用及案例分析     

韩宏志  官鑫  李欣欣  姜瑾秋  王丽 《编辑学报》2018,30(6):586-588

logistic回归分析在医学研究领域应用较为广泛,但因其涉及的因素较多,统计方法较为复杂,部分研究者未咨询流行病学和卫生统计学专业人员而盲目套用统计学方法,造成其在应用logistic回归分析处理数据时出现诸如自变量选取和纳入、统计模型选择、结果表述和报告时误用错用情况的发生。本文选取公开发表的医学论文,举例分析文章中logistic回归误用错用的情况,指出其正确应用方法,为医学期刊编辑处理类似稿件提供参考。  相似文献   

Could scientists use Altmetric.com scores to predict longer term citation counts?     

Mike Thelwall  Tamara Nevill 《Journal of Informetrics》2018,12(1):237-248

Altmetrics from Altmetric.com are widely used by publishers and researchers to give earlier evidence of attention than citation counts. This article assesses whether Altmetric.com scores are reliable early indicators of likely future impact and whether they may also reflect non-scholarly impacts. A preliminary factor analysis suggests that the main altmetric indicator of scholarly impact is Mendeley reader counts, with weaker news, informational and social network discussion/promotion dimensions in some fields. Based on a regression analysis of Altmetric.com data from November 2015 and Scopus citation counts from October 2017 for articles in 30 narrow fields, only Mendeley reader counts are consistent predictors of future citation impact. Most other Altmetric.com scores can help predict future impact in some fields. Overall, the results confirm that early Altmetric.com scores can predict later citation counts, although less well than journal impact factors, and the optimal strategy is to consider both Altmetric.com scores and journal impact factors. Altmetric.com scores can also reflect dimensions of non-scholarly impact in some fields.  相似文献   

试论影响组织设计过程中的关键因素     

耿乃国 《继续教育研究》2006,(1):159-160

组织设计是确定适合组织的战略、组织成员、技术和组织任务等组织结构的过程。组织设计五项经典原则一直在组织设计中发挥着指导性作用,但在组织设计过程中,对一些关键因素,如:组织战略目标、组织环境变化、组织的成长性与稳定性、组织的核心能力、组织的可塑性、组织所处环境的文化价值观等仍是我们在组织设计中要给予重视的关键因素。  相似文献

Child sexual abuse as reported by Israeli adolescents: Social and health related correlates     

《Child abuse & neglect》2015

The objectives of the study were to assess the prevalence of child sexual abuse (CSA) in a nation-wide representative sample of 14–17 year old Israeli adolescents, and to examine the associations between CSA, socio-demographic correlates and various measures of physical and mental health. The study population consisted of 906 mother–adolescent dyads, belonging to a community based, representative sample of Israeli 14–17 year olds, interviewed in 2004–5. Response rate was 68%. Subjects provided demographic data, and information about CSA, physical symptoms, body image, well-being and use of mental health services. DAWBA was used to obtain information regarding mental disorders and suicidality. SDQ was used to obtain data on bullying. Statistical analyses were conducted using an SPSS-17 complex sample analysis module and multivariate analyses were conducted to assess the associations between CSA and risk factors and social and health related correlates. Findings show that CSA was reported by 3.3% of adolescents. Higher risk of exposure to CSA was found among girls, among adolescents living in a one-parent household and among adolescents with a chronic disability. In multivariate models adjusting for gender, learning disabilities and depression, CSA was associated with suicidal attempts, stomach ache, dizziness, sleep problems, well being at home and bullying behaviors. No association was found with suicidal ideation or other physical symptoms. Our findings confirm that the associations between CSA and different outcomes vary depending on the socio-psychological context, and underline the importance of addressing the complexity of variables associated with CSA.  相似文献   

基于对应分析模型原理的户外运动安全风险研究     

欧雅怡  刘〓亚  马逢伯 《广州体育学院学报》2017,37(2):43-48

通过对我国2001年至2014年期间,258个户外运动安全事故案例的统计和分析,结合国内外相关研究,建立户外运动安全风险分析框架,将户外运动安全风险划分为4个维度,18个因素指标.根据对应分析模型原理,深入研究户外运动中季节、月份与时段风险的对应性关系,R(3.2.0)软件运行结果显示:户外运动中,凌晨和晚上的风险指数最高;春季、秋季的上午和下午时段,可能存在的伤亡风险几率较高;5月、9月、10月的上午和晚上,3月、6月、11月、12月的下午,1月和4月的凌晨时段,可能存在的伤亡风险几率更高.使用Minitab软件,根据累积贡献率80％以上为主要因素的帕累托原则得到8个主要风险因素和7个次要风险因素.  相似文献   

Fatigue increases ankle sprain risk in badminton players: A biomechanical study     

Alexis Herbaut  Julien Delannoy 《Journal of sports sciences》2020,38(13):1560-1565

ABSTRACT

Ankle sprains are the most common injury in regular badminton players and usually occur at the end of a match or training. The purpose of the present study was to examine the influence of fatigue produced by badminton practice on the lower limb biomechanics of badminton players. It was hypothesized that fatigue induces ankle kinematic and lower leg muscle activity changes which may increase the risk of ankle sprain. Ankle kinematics, ankle kinetics and muscles activities of 17 regular badminton players were recorded during lateral jumps before and after an intense badminton practice session. Post-fatigue, ankle inversion at foot strike and peak ankle inversion increased (+2.6°, p = 0.003 and +2.5°, p = 0.005, respectively). EMG pre-activation within 100 ms before foot landing significantly decreased after fatigue for soleus (?23.4%, p = 0.031), gastrocnemius lateralis (?12.2%, p = 0.035), gastrocnemius medialis (?23.3%, p = 0.047) and peroneus brevis (?17.4%, p = 0.036). These results demonstrate impaired biomechanics of badminton players when fatigue increases, which may cause a greater risk of experiencing an ankle sprain injury.  相似文献   

Screening for risk of low energy availability in athletic and recreationally active females in Ireland     

Danielle M. Logue  Sharon M. Madigan  Mirjam Heinen  Sarah-Jane McDonnell  Eamonn Delahunt  Clare A. Corish 《European Journal of Sport Science》2019,19(1):112-122

ABSTRACT

Introduction: Low energy availability (LEA) results in physiological adaptations, which can contribute to unfavourable health outcomes. Little information exists on risk of LEA in active individuals competing in different sports or levels of competition. The aims of this study were to (1) identify risk of LEA in females competing at different levels of competition and (2) investigate associations between risk of LEA, illness and dietary habits. Methods: The validated questionnaire, ‘Low Energy Availability in Females Questionnaire’ was distributed online (November 2016–February 2017) to assess risk of LEA. Twenty-nine additional questions collected information on demographics, illness history and dietary habits. Participants were considered at risk of LEA if they attained a score of?≥?8 and were grouped into: (i) international; (ii) provincial/inter-county; (iii) competitive; and (iv) recreationally active. Chi-square and logistic regression analyses were used to explore differences between those at risk or not at risk of LEA. Results: Risk of LEA was identified in 40% (n?=?331) of 833 participants and was 1.7 and 1.8 times more likely in international and provincial/inter-county athletes compared to those who were recreationally active (International: odds ratios (OR) 1.68, 95% confidence intervals (95%CI) 1.12–2.54; Provincial/inter-county: OR 1.83, 95%CI 1.20–2.77). In participants at risk of LEA, missing >22 days of training during the previous year due to illness occurred 3 times more frequently (OR 3.01, 95%CI 1.81–5.02). Conclusion: Risk of LEA was widespread in this heterogeneous sample. Awareness of LEA and the development of appropriate energy management strategies to ensure athlete health across levels of competition are required.  相似文献   

中国城市生活资源消耗与污染排放的主要影响因素   总被引：1，自引：0，他引：1  

杨晓娇  王效科 《中国科学院大学学报》2019,36(5):626-632

资源环境的保障程度直接影响中国城市化的速度与质量，制约着城市化的可持续发展。运用相关分析和冗余分析方法，研究2014年全国省会城市生活资源消耗和污染排放的主要影响因素。结果表明：1）中国省会城市生活资源消耗的主要影响因素是气候（解释变异量为0.40），其次是经济发展水平（0.14）和城市规模（0.11）。2）污染排放的主要影响因素是城市规模（解释变异量为0.21），其次是经济发展水平（0.17）和气候（0.16）。因此，针对城市资源消耗和污染排放的影响因素，制定适宜的资源开发和环境治理政策，对中国城市的可持续发展具有重大意义。  相似文献
