Treat-and-extend dosing of intravitreal anti-VEGF agents in neovascular age-related macular degeneration: a meta-analysis.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Intravitreal injections of antiangiogenic agents are pivotal in treating neovascular age-related macular degeneration (nAMD). The comparative efficacy and safety of treat-and-extend (T&E) versus bimonthly, monthly, and pro re nata (PRN) dosing remains unclear. A systematic review and meta-analysis of English-language RCTs reporting on efficacy and/or safety outcomes of dosing regimens of anti-VEGF agents in nAMD was performed. Best-corrected visual acuity (BCVA, ETDRS letters) at last follow-up represented the primary endpoint, while central subfield thickness (CSFT, μm), injection burden, and ocular adverse events were secondary endpoints. A random effects meta-analysis was performed, and 95% confidence intervals were calculated. Across six RCTs, 781 T&E-, 663 monthly-, 130 PRN-, and 123 bimonthly treated eyes were included. Mean changes in BCVA and CSFT at last follow-up were similar between T&E versus monthly (WMD, -0.62 letters; 95% CI, -2.12 to 0.87; P = 0.41; WMD, 5.30 microns; 95% CI, -10.67 to 21.26; P = 0.52, respectively), bimonthly (WMD, 1.68 letters; 95% CI, -3.55 to 6.91; P = 0.53; WMD, -18.91 microns; 95% CI, -46.41 to 8.60; P = 0.18, respectively), and PRN (BCVA WMD, 1.08 letters; 95% CI, -2.95 to 5.11; P = 0.60) regimens. T&E was associated with a reduced injection burden versus monthly (WMD, -4.52 injections; 95% CI, -6.66 to 2.39; P < 0.001) but higher injection burden versus PRN (WMD, 1.81 injections; 95% CI, 1.12 to 2.51; P < 0.001) dosing. There was no significant difference in safety outcomes amongst comparators. There was no significant difference in efficacy and safety between T&E, bimonthly, monthly, and PRN dosing. T&E resulted in fewer injections versus monthly and fewer clinic visits versus PRN.
