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
purposeThe purpose of this study was to quantitatively assess changes in the subfoveal choroidal thickness (SFCT) and superficial retinal vessel density (SRVD) in acute and chronic central serous chorioretinopathy (CSCR) patients, and estimate the correlation of SFCT and SRVD with best-corrected visual acuity (BCVA), respectively, using spectral domain optical coherence tomography (SD-OCT) and optical coherence tomography angiography (OCTA).
methodsThis was a cross-sectional, case-control study. The study included CSCR patients treated at the Ho Chi Minh City Eye Hospital from May 2022 to October 2022.
resultsA total of 91 subjects (182 eyes) were included in this study, with 74 eyes in the unilateral acute CSCR group and 17 eyes in the unilateral chronic CSCR group; 91 eyes in the control group were patients' unaffected other eyes. The mean age was 40.78 ± 1.26 years (ranging from 31 to 45 years). The proportions of male and female patients were 78.0% and 22.0%, respectively. The major symptom was reduced vision, and the mean BCVA was 0.36 ± 0.05 logMAR. The mean SFCT of CSCR eyes was 357.2 ± 11.8 μm, which was 290.4 ± 8.5 μm in the control group (p < 0.05). The mean SRVD of chronic CSCR (24.2 ± 4.94%) and acute CSCR (28 ± 2.33%) eyes was lower compared with the control group (21.7 ± 1.87%). SFCT had a correlation with BCVA (r = -0.490, p < 0.05) in chronic CSCR; the center region of SRVD was likewise correlated with BCVA (r = -0.384, p < 0.05) and the parafoveal region of SRVD was also correlated with BCVA (r = -0.271, p < 0.05).
conclusionBoth altered SFCT and SRVD were identified in CSCR patients by SD-OCT and 6 x 6 mm OCT angiography scans, and both were found to be correlated with BCVA. SD-OCT along with OCTA could be a good technique for quantitatively evaluating different CSCR courses.
