Constructed model is sex = β × adjacent FWLC difference + constant, the cut up value is 0.5 (that is predictive probability is for female group membership). Value ≤ 0.5 is indicative of male gender and value > 0.5 is indicative of female gender, d difference, R right, L left, 1–5 first to fifth digits. * This indicates the best adjacent FWLC differences that predict sex (based on stepwise (forward conditional) multiple binary logistic regression analyses). Adj. DFWLCD adjacent digit fingerprint white line counts difference
