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
introductionThis study investigated the long-term natural history of peripapillary pachychoroid syndrome (PPS), analyzing both morphological and functional outcomes.
methodsThis retrospective study included 24 eyes from 14 participants diagnosed with PPS. No interventions were administered. Baseline and follow-up assessments comprised best-corrected visual acuity (BCVA), measured on the LogMAR scale, inner nasal (IN) and outer nasal (ON) macular thickness measured using the ETDRS (Early Treatment Diabetic Retinopathy Study) subfields. To account for repeated measures and the hierarchical structure of eyes nested within participants, and to appropriately handle incomplete longitudinal data, linear mixed-effects models were utilized for all statistical analyses.
resultsThe mean age was 74 ± 7 years, and 71% of patients had bilateral PPS. All patients had peripapillary atrophy at baseline. The mean baseline BCVA was 0.05 and showed only small variations over time. ON macular thickness showed a significant decrease at 2 years (Δ = - 36.9 µm, p = 0.034), whereas IN macular thickness decreased significantly at both 2 years (Δ = - 40.75 µm, p = 0.023) and 3 years (Δ = - 39.97 µm, p = 0.042). One-quarter of participants developed a serous pigment epithelium detachment with subretinal fluid, suggesting an overlapping PPS/CSC (central serous chorioretinopathy) phenotype.
conclusionsPeripapillary atrophy appears to be an important anatomical predisposition for PPS. Waxing and waning of intraretinal fluid were observed during the natural course of PPS, with a significant reduction at 2 years. Most patients remained asymptomatic and maintained stable BCVA throughout long-term follow-up, indicating a generally favorable prognosis in the absence of intervention.
