Right and left bias frequencies in humeral TA and J by time period and sex.

N = total number of paired humeri; R = number of individuals with right-dominance (+%DA);L = number of individuals with left-dominance (-%DA); p values reflect X2 tests for significant;right-biasing relative to what would be expected by chance; ns = not significant at pRight and left bias frequencies in humeral TA and J by time period and sex.N为配对肱骨的总数量；R为呈现右侧优势的个体数（+%DA）；L为呈现左侧优势的个体数（-%DA）；p值为针对相较于随机预期的右侧偏倚的卡方（X²）检验显著性结果；ns代表在对应显著性水平下无统计学意义；本数据集涵盖按时间阶段与性别分组的肱骨TA与J的左右偏倚频率数据。
