Since seven of our OS participants left our study before taking this (grapheme-personification) synaesthesia test, we repeated our analysis with the conservative assumption that all were non-synaesthetes and this still resulted in a strong trend for a higher prevalence of confirmed grapheme-personification synaesthesia for gender associations in the OS group compared to controls, χ 2 (1) = 3.618, p = 0.057, 95% CI [−0.004, 0.30].
