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.

Abstract
Purpose: To report efficacy of intravitreal pegcetacoplan treatment over 36 months in eyes with subfoveal geographic atrophy (GA). Patients and Methods: The GALE (NCT04770545) open-label extension trial adds 12 months of results to the 24-month Phase 3 OAKS (NCT03525613) and DERBY (NCT03525600) trials, representing up to 36 months of continuous pegcetacoplan treatment. They included a heterogeneous population of eyes with subfoveal GA (63%). Pegcetacoplan-treated eyes enrolling in GALE continued at the same interval of pegcetacoplan monthly (PM) or every other month (PEOM). Patients' eyes in sham monthly or every-other-month arms crossed over to receive pegcetacoplan in GALE at the same interval (sham crossover). Consequently, projected sham, calculated from prior 24-month GA growth rate of sham-observed eyes in OAKS and DERBY averaged across four 6-month segments, was the comparator for the first 12 months of GALE (months 24-36). This analysis reports results of eyes with subfoveal GA at baseline. Results: In eyes with subfoveal GA, 84% had best corrected visual acuity (BCVA) ≥20/200 and 38% had BCVA ≥20/63 at OAKS and DERBY baseline. Pegcetacoplan reduced subfoveal GA growth rate by 21% (p<0.0001) with PM and 19% (p=0.0001) with PEOM over 36 months. Increasing efficacy over time was noted between months 24 and 36; 31% reduction in subfoveal GA growth rate with PM and 25% reduction with PEOM (both p<0.0001) compared with projected sham. Microperimetry demonstrated significant reduction in formation of absolute scotomas with PM at 24 months (-2.5 number of scotomas formed; 95% confidence interval [CI]: -4.5, -0.4; p=0.0205) and 36 months (-4.0 number of scotomas formed; 95% CI: -6.8, -1.2; p=0.0050), compared to sham crossover in subfoveal GA. Safety profile in GALE was consistent with OAKS and DERBY. Conclusion: Long-term efficacy of pegcetacoplan in slowing GA progression was demonstrated over 36 months in eyes with subfoveal GA.
