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
Purpose: To quantify macular pigment optical density (MPOD) in eyes with lamellar macular holes (LMHs) diagnosed according to contemporary optical coherence tomography (OCT) criteria and to evaluate its relationship with structural and functional parameters. Methods: This prospective observational study screened 66 patients with unilateral LMH. All participants underwent comprehensive ophthalmic examination, spectral-domain OCT, and MPOD assessment using heterochromatic flicker photometry. Central foveal thickness (CFT), best-corrected visual acuity (BCVA) and OCT features were recorded. Paired inter-eye comparisons and linear mixed-effects regression analyses were performed. Results: Forty-eight patients (48 LMH eyes and 48 contralateral healthy fellow eyes) were included. CFT was significantly reduced in LMH eyes compared with fellow eyes (177.2 ± 13.6 µm vs. 251.9 ± 5.9 µm; P < 0.0001). MPOD was lower in LMH eyes than in fellow eyes (0.508 ± 0.096 vs. 0.583 ± 0.097; P < 0.0001), and BCVA was worse (P < 0.0001). In multivariable analysis restricted to LMH eyes, MPOD was independently associated with age (β = -0.010 per year; 95% CI, -0.018 to -0.003; P = 0.0085) and BCVA (β = -0.494 per logMAR; 95% CI, -0.910 to -0.079; P = 0.0207), but not with CFT (P = 0.1438). In eyes with marked foveal thinning (CFT < 180 µm; n = 26), MPOD was reduced (P = 0.0065). Conclusions: MPOD is reduced in eyes with OCT-defined LMH and is associated with BCVA. As MP is preferentially localized within the Müller cell cone, altered MPOD may reflect foveal remodeling or MP redistribution related to EP.
