∗for baseline visual acuity, P values for IVT versus IVB are for the baseline values themselves; the other P values are for the change achieved with the two drugs relative to the baseline values. BCVA: best corrected visual acuity; LogMAR: logarithm of the minimal angle of resolution; IVT: intravitreal triamcinolone; GLP: grid laser photocoagulation; IVB: intravitreal bevacizumab; ∗P value less than 0.05 was considered statistically significant.
