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
purposeAge-related macular degeneration (AMD) and retinal vein occlusion (RVO) share common risk factors and the risk of blindness is higher when both diseases coexist. This study aims to evaluate the risk factors of developing RVO among AMD patients and describe their clinical characteristics.
methodsIn this single-center cohort study, 5618 Patients with AMD were divided into two groups: those who developed RVO and those who did not. Demographic, clinical and comorbidity profile were compared and multivariable logistic regression was performed to identify risk factors for RVO among patients with AMD. Additionally, baseline characteristics were compared between patients who developed central and branch retinal vein occlusion (CRVO and BRVO).
resultsAmong 5,618 patients with AMD, 55 developed RVO while 5563 did not. The prevalence of RVO among AMD patients was 9.79/1,000 AMD patients (95% CI:7.2-12.4) with an incidence rate of 2.04/1,000 person-years. Multivariate regression analysis revealed patients with lower BMI(OR:0.89,95%CI:0.84-0.95,p = < 0.001), higher Charlson comorbidity index(OR:1.12,95%CI:1.02-1.22,p = 0.019), African-American ethnicity(OR:4.07,95%CI:1.55-10.73,p = 0.004), glaucoma(OR:2.09,95%CI:1.2-3.64,p = 0.009) and neovascular AMD(OR:1.92,95%CI:1.07-3.43,p = 0.028) have higher risk. On subgroup analysis, 27 patients developed CRVO, while 29 developed BRVO. The mean time to RVO development after the first visit for AMD was 4.42±3.6 years. Patients with CRVO had significantly worse visual acuity(p < 0.001), higher IOP(p = 0.012), and a higher incidence of glaucoma(p = 0.006) at baseline.
conclusionAMD Patients with lower BMI, higher CCI, African Americans, glaucoma, and neovascular AMD are at a higher risk of developing RVO. Identifying these risk factors is crucial to diagnose RVO promptly in patients with AMD as it has a higher prevalence compared to the general population, with a greater risk for vision loss.
