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 determine the postoperative subfoveal choroidal vascular index (SFCVI) in patients who underwent pars plana vitrectomy (PPV) for rhegmatogenous retinal detachment. Patients who underwent PPV for rhegmatogenous retinal detachment were included in the study. Spectral-domain optical coherence tomography (SD-OCT), including the foveal center, was performed in all patients at the first, third, and sixth months after surgery. This study included 28 patients who underwent PPV for RRD. In 16 eyes, 1000cSt silicone oil (57.1%) and in 12 eyes (42.9%), perfluoropropane (C3F8) gas were utilized as tamponade agents. A statistically significant difference was observed in the SFCVI value between the C3F8 and silicone group at the 3rd month (p = 0.034), but this difference was not significant in the 6th month (p = 0.205). SFCVI was significantly lower in the gas-treated eyes than in the control eyes of the same patients only in the first month (p = 0.003), whereas no significant differences were found in other periods. A comparison of the SFCVI values at the first, third, and sixth months in the silicone group with those in the control group revealed no significant differences (p = 0.65, 0.52, and 0.50, respectively). There was no significant correlation between SFCVI values and BCVA, IOP, and SFCT values in the postoperative examinations of eyes that underwent PPV due to retinal detachment (p > 0.05). Although SFCVI decreases in the early period in patients given C3F8 as tamponade, it returns to normal levels in the late period. New studies are needed to evaluate the possible functional and anatomical consequences of this temporary decrease in the long term.
