Regression analyses of each association between different measures of handedness and components of reproductive success.

B’s, standard errors (SE), Wald Chi square statistics and p-values are presented. Results of the interaction effects are reported from the full models whereas those of the main effects are from models without the interaction effects. The models additionally include age, age2, and the total score on the task (L+R) in the models concerning the pegboard or ball throwing task. For more details please refer to the text.本研究报告了B值、标准误（standard errors，SE）、沃尔德卡方统计量与p值。其中，交互效应的结果取自全模型，主效应的结果则来自未包含交互效应的模型。针对钉板任务或投球任务的模型，额外纳入了年龄、年龄平方（age2）以及任务总得分（L+R）。更多细节请参阅正文。
