Table 5 Logistic regression analyses of children’s 2D:4D ratios (bottom 10 %): comparison of children scoring high and low on emotion recognition (DANVA) and social communication (SCDC)

From: Social communication and emotion difficulties and second to fourth digit ratio in a large community-based sample

  1. Higher scores on SCDC represent more social communication problems. Higher scores in DANVA means more mistakes are made when identifying emotions/more misattributionss
