MCNT, mathematics, computer science, natural sciences, and technical studies; ES, psychology, economics and empirical social ciences; HT, humanities and theology. Due to missing values based on partially different case numbers: medicine n = 338–339; MCNT n = 659–661, other degree programs n = 164–165, ES n = 267–268, HT n = 506–507, law n = 199–200. Significance value p of the test for equality of the relative frequencies of the individual syndromes in the subjects; Fisher's exact test, hybrid form according to Mehta and Patel [16].
