  1. Means and standard deviations (SD) of the morphological second digit to fourth digit (2D:4D) ratio, maximal voluntary contraction (MVC) of total finger force, and enslaving index (EN) are presented. Subscripts denote: I, index; M, middle; R, ring; L, little fingers. Double asterisks denote a significant difference between ASD and control groups, p < 0.01 after Bonferroni correction.
