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 determine the optimal cut-offs for Pelli-Robson (PR) and Spaeth/Richman contrast sensitivity (SPARCS) test scores for diagnosing glaucoma and to compare PR and SPARCS scores (total and individual quadrants) for assessing contrast sensitivity in patients with glaucoma. Methods: This study was a single-center, cross-sectional, two-group analysis of 87 glaucomatous eyes and 87 non-glaucomatous control eyes. We assessed visual acuity, refraction, intraocular pressure (IOP), cup disc ratio (CDR), and anterior chamber depth in these patients. The PR score for central contrast sensitivity was obtained, and the SPARCS scores were generated for four outer zones and the central region. Results: The mean IOP [SD] was significantly higher in the glaucoma group (19.3 [5.2] mm Hg) compared with the control group (17.5 [3.6] mm Hg; Conclusion: At the optimal cut-offs, the total SPARCS score offers significantly better diagnostic test properties for identifying glaucoma compared with the PR score.
