Downregulation of angiogenic factors in aqueous humor associated with less intraoperative bleeding in PDR patients with NVG receiving conbercept: a randomized controlled trial

Table 1 Demographic characteristics of the study subjects and the control group

	Control (n = 19)	Group I (n = 18)	Group II (n = 16)	P value
Age	59.47 ± 12.27	55.56 ± 12.56	56.06 ± 9.44	0.541^a
Men, n (%)	8 (42.11)	13 (72.22)	9 (56.25)	0.181^b
Right Eye, n (%)	7 (36.84)	11 (61.11)	7 (43.75)	0.318^b
Preoperative IOP (mmHg)	15.42 ± 3.37	46.06 ± 10.36^c	45.88 ± 11.56^c	0.000^a

^a One-way analysis of variance with post hoc LSD multiple comparison tests were performed to compare the age and preoperative IOP among the three groups
^b The difference of the sex and eye distribution among the three groups were measured by χ² test
^c Compared with control, P < 0.001
