Morphometric variations and nonmetric anatomical traits or anomalies of the primary molar teeth, plus the molars' size thresholds for sex identification

Table 8 The results of the Spearman correlation coefficient, testing correlations among the occurrences of the traits (coded as absent = 0, unilateral = 1, or bilateral = 2) in the primary mandibular second molars. N for each correlation is 79
