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: The purpose of this study was to simultaneously visualize cone photoreceptors (cone) and retinal pigment epithelium (RPE) cells at the cellular level in Stargardt disease (STGD) using adaptive optics (AO) imaging. In addition, the feasibility of quantitative analysis was explored. Design: Observational case series. Subjects: Patients with STGD. Methods: Cone and RPE cells were simultaneously imaged at the cellular level using AO flood-illumination ophthalmoscopy (AO-FIO) and AO transscleral flood illumination (AO-TFI). Quantitative metrics were derived and normalized as z-scores to provide an exploratory assessment of the feasibility of cellular-level quantification. Main Outcome Measures: Cellular-level cone and RPE integrity and abnormalities assessed by simultaneous AO-FIO and AO-TFI imaging. Results: Using AO-FIO and AO-TFI, cone and RPE cells could be simultaneously visualized in eyes with STGD. In a subset of cases, cellular-level quantitative analysis was feasible. Imaging findings varied across patients and retinal regions, showing heterogeneous degrees of structural alteration in cone and RPE cells. In the quantitatively analyzed cases, cone density z-scores showed marked reductions, with the lowest values of -3.28 in case 1 and -2.90 in case 2, whereas RPE cell density z-scores showed only mild deviations and remained within the reference range in the analyzed regions. Conclusions: Adaptive optics flood-illumination ophthalmoscopy and AO-TFI enable simultaneous cellular-level visualization of cone and RPE cells in STGD. This study characterized cellular-level structural features in STGD and demonstrated the feasibility of quantitative analysis in a subset of cases. These findings could contribute to a deeper understanding of STGD pathology and support future investigations aimed at treatment optimization.
