Changes in personality scores in the escitalopram and the placebo group following four weeks of treatment.

a) The distributions did not differ significantly from the normal distribution (Shapiro Wilkes test) and a t-test was used to compare the escitalopram and the placebo arm. P of Levene's test ranged from 0.11 to 0.80.
b) The distributions differed from the normal distribution but judged from the graphical displays (histograms and probability distributions) they followed normal distributions with reasonable approximation, thus a t-test was also used.
c) Eysenck: Escitalopram (n = 39), placebo (n = 37).
d) NEO-PI-R: Escitalopram (n = 39), placebo (n = 38).
