Gender difference in QTc prolongation of people with mental disorders

Table 3 Gender difference in QTc interval when the factor significant in two-way ANCOVA is fixed.

Factor significant in two-way ANCOVA	Mean (SD) of QTc interval	F-value
cardiovascular disease
absent (n = 277)		10.251**
Male (n = 122)	0.398 (0.035)
Female (n = 155)	0.411 (0.036)
present (n = 51)		0.353
Male (n = 23)	0.421 (0.034)
Female (n = 28)	0.420 (0.037)

One-way ANCOVA (analysis of covariance): Gender was included as a factor, QTc interval as a dependent variable, and age at admission as a covariate. There was only one factor significant in two-way ANCOVAs (cardiovascular disease), and it has two categories (absent, and present), therefore 2 tests were performed in total. **p < 0.01.
