Table 2: Statistical significance in retinal sensitivity and fixation stability between groups

	Group A n=8	Group B n=12	Group C n=5	Controls n=25	P-value
Mean sensitivity (dB)	15.65	14.74	14.9	17.53	0.09
SD	4.83	3.32	7.12	1.99
Mean logBCEA (deg2)	-0.63	-0.16	-0.75	-0.67	0.01
SD	0.36	0.47	0.27	0.42
dB: Decibel; BCEA: Bivariate Contour Ellipse Area; Group A: SSRI/SNRI + atypical antipsychotic drugs; Group B: SSRI/SNRI monotherapy; Group C: pharmacological washout; Differences between groups were estimated using Kruskal-Wallis test.P value less than 0.05 were considered statistically significant, and P< 0.001 was considered to be highly statistically significant.
