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
Objective: To investigate the association between the posterior precortical vitreous pocket (PPVP) and retinal morphological and blood flow parameters, with the aim of elucidating its potential pathophysiological significance. Methods: This prospective single-center study included 65 healthy subjects. PPVP was assessed using spectral-domain optical coherence tomography (OCT) and optical coherence tomography angiography (OCTA). The associations between PPVP presence and macular retinal thickness, volume, and vessel density were analyzed. Results: PPVP was detected in 72.3% (47/65) of subjects. Compared with the PPVP-negative group, the PPVP-positive group showed significantly greater retinal thickness in the superior inner macula (362.91 ± 16.84 vs. 344.06 ± 15.59 μm, Conclusion: The presence of PPVP was significantly associated with localized retinal thickening, increased retinal volume, and enhanced retinal blood flow. These findings suggest that PPVP may influence the vitreoretinal interface through biomechanical or microcirculatory mechanisms. This study systematically characterizes the morphological and functional features associated with PPVP and may contribute to a better understanding of the physiological vitreoretinal interface, with potential implications for future research into related retinal disorders.
