Pro re nata versus fixed aflibercept regimen for neovascular age-related macular degeneration: a systematic review and meta-analysis.
Review in International journal of retina and vitreous, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
backgroundAflibercept is a relatively new anti-VEGF used to treat neovascular age-related macular degeneration (AMD). The purpose of this review is to evaluate the effect of pro re nata (PRN) and fixed regimen (bimonthly) of aflibercept injection for neovascular AMD on visual outcomes at 12 months of follow-up.
methodsWe conducted a systematic search in PubMed (MEDLINE), Embase, Scopus, and Web of Science, EBSCOHost, and ClinicalTrials.gov databases. Number of injections, number of hospital visit, mean change of best corrected visual acuity (BCVA), mean change of central macular thickness (CMT), and adverse effects of the included studies were evaluated. Meta-analysis were performed using Review Manager 5.4.
resultsFour studies were selected for meta-analyses synthesis (3 RCT, 1 retrospective study). A total of 197 eyes in PRN group and 241 eyes in the fixed group. All four studies favored fixed regimen with standardized mean difference of 0.56 (95% CI 0.36-0.75, I
conclusionThe present meta-analysis shows that bimonthly injection of aflibercept for neovascular AMD is superior compared to PRN injection, shown by better improvement in BCVA at 12 months follow-up. However, high risk of bias downgrade the certainty of evidence.
