We did not impose any day or language restrictions in electronic searches for tests. Selection criteria We included randomized controlled tests (RCTs) that evaluated pegaptanib, ranibizumab, or bevacizumab versus each other or versus a control treatment (e.g. sham treatment, photodynamic therapy), in which participants Rabbit Polyclonal to TFE3 were adopted for at least one year. Data collection and analysis Two evaluate authors individually screened records, extracted data, and assessed risks of bias. We contacted trial authors for more data. We compared results using risk ratios (RRs) or imply variations (MDs). We used the standard methodological procedures expected by Cochrane. Main results We included 16 RCTs that experienced enrolled a total of 6347 participants with neovascular AMD (the number of participants per trial ranged from 23 to 1208) and recognized one potentially relevant ongoing trial. Six tests compared anti\VEGF treatment (pegaptanib, ranibizumab, or bevacizumab) versus control, and 10 tests compared bevacizumab versus ranibizumab. Pharmaceutical companies carried out or sponsored four tests but funded none of them of the studies that evaluated bevacizumab. Researchers carried out these tests at numerous centers across five continents (North and South America, Europe, Asia, and Australia). The overall certainty of the evidence KU 59403 was moderate to high, and most tests had an overall low risk of bias. All but one trial had KU 59403 been authorized prospectively. When compared with those who received control treatment, more participants who received intravitreous injection of any of the three anti\VEGF providers had gained 15 characters or more of visual acuity (risk percentage [RR] 4.19, 95% confidence interval [CI] 2.32 to 7.55; moderate\certainty evidence), had lost fewer than 15 characters of visual acuity (RR 1.40, 95% CI 1.27 to 1 1.55; high\certainty evidence), and showed imply improvement in visual acuity (imply difference 6.7 characters, 95% CI 4.4 to 9.0 in one pegaptanib trial; imply difference 17.8 characters, 95% CI 16.0 to 19.7 in three ranibizumab tests; moderate\certainty evidence) after one year of adhere to\up. Participants treated with anti\VEGF providers showed improvement in morphologic results (e.g. size KU 59403 of CNV, central retinal thickness) compared with participants not treated with anti\VEGF providers (moderate\certainty evidence). No trial directly compared pegaptanib versus another anti\VEGF agent and adopted participants for one yr; however, when compared with control treatments, ranibizumab and bevacizumab each yielded larger improvements in visual acuity results than pegaptanib. Visual acuity results after bevacizumab and ranibizumab were related when the same RCTs compared the same regimens with respect to gain of 15 or more characters of visual acuity (RR 0.95, 95% CI 0.81 to 1 1.12; high\certainty evidence) and loss of fewer than 15 characters of visual acuity (RR 1.00, 95% CI 0.98 to 1 1.02; high\certainty evidence); results showed related mean improvement in visual acuity (mean difference [MD] \0.5 characters, 95% CI \1.5 to 0.5; high\certainty evidence) after one year of adhere to\up, despite the considerably lower cost of bevacizumab compared with ranibizumab. Reduction in central retinal thickness was less among bevacizumab\treated participants than among ranibizumab\treated participants after one year (MD \11.6 m, 95% CI \21.6 to \1.7; high\certainty evidence); however, this difference is within the range of measurement error, and we did not interpret it to be clinically meaningful.
