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
backgroundThis study aimed to evaluate changes in choriocapillaris (CC) perfusion in patients with chronic central serous chorioretinopathy (cCSC) following treatment with half-dose photodynamic therapy (PDT), using swept-source optical coherence tomography angiography (SS-OCTA).
methodsThis pilot study included patients diagnosed with cCSC who underwent half-dose PDT using the Visulas 690s PDT Laser System (Carl Zeiss Meditec, Inc., Jena, Germany; 689-nm wavelength, 50J/cm², 83s). Fovea-centered OCTA scans (6 × 6mm) were obtained using the Zeiss Plex Elite 9000 SS-OCT system. OCTA assessments were conducted at baseline prior to treatment and 6 months post-treatment. The primary outcome was the percentage of choriocapillaris flow deficits (FD%) on OCTA. Secondary outcomes included best-corrected visual acuity (BCVA), central macular thickness (CMT), and subfoveal choroidal thickness (SFCT).
resultsThe study included 23 eyes from 23 patients with cCSC, with a mean age of 46.3 ± 2.1 years, of which 16 out of 23 were men. Significant improvements were observed in all parameters at 6 months. The FD% decreased significantly from 28.9 ± 2.2% at baseline to 26.4 ± 1.9% after 6 months (p = 0.023). BCVA improved from 0.28 ± 0.13 LogMAR to 0.22 ± 0.11 LogMAR (p = 0.025). Both CMT and SFCT showed significant reductions (p < 0.05). After 6-months, SRF was resolved in 21 out of 23 eyes (91.3%) included in the analysis, while the remaining two eyes showed a reduction of SRF.
conclusionHalf-dose PDT was effective in improving CC perfusion and other morpho-functional parameters in eyes with cCSC. These findings provide valuable insights into the potential mechanisms through which PDT may influence the progression of cCSC.
