for baseline CRT, values for IVT versus IVB are for the baseline values themselves; the other values are for the change achieved with the two drugs relative to the baseline values. CRT: central retinal thickness; vs: versus; IVT: intravitreal triamcinolone; GLP: grid laser photocoagulation; IVB: intravitreal bevacizumab; P value less than 0.05 was considered statistically significant.
