Factors related to changes in visual symptoms after successful photodynamic therapy in central serous chorioretinopathy.
Article in PloS one, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
To investigate biomarkers related to visual symptom and best corrected visual acuity (BCVA) improvement after photodynamic therapy (PDT) for central serous chorioretinopathy. This retrospective cross-sectional study involved 42 consecutive eyes, from 42 patients who underwent successful PDT, divided into two groups according to improvement in subjective visual complaints: complete (20 eyes) and incomplete recovery (22 eyes). The clinical characteristics of each group, including central foveal thickness (CFT), foveal avascular zone (FAZ) area, and degree of change in signal voiding of the choriocapillaris on optical coherence tomography angiography, were compared. Correlations between best-corrected visual acuity (BCVA) and baseline clinical features were investigated. At baseline, CFT and FAZ areas showed significant differences between the two groups (all p < 0.05). Multiple binary logistic regression analysis revealed that greater CFT predicted complete recovery from visual complaints (p = 0.002). Reduction or disappearance of signal voiding in the choriocapillaris 6 months post-PDT occurred more frequently in the complete recovery group (p < 0.05). FAZ area before PDT correlated with BCVA before and 6 months after PDT and BCVA improvement during the study period (all p < 0.05). CFT and FAZ area before PDT correlated with completeness of visual symptom recovery after PDT. Smaller FAZ area before PDT correlated with better BCVA before and after treatment.
