1 · What the graph read from it

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.

2 · The registry

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

backgroundTo compare the effect of corneal rigid and scleral contact lenses (CRCL & SCL) on binocular vision and accommodative function in keratoconus (KCN) patients.

methodsIn this prospective non- randomized comparative interventional study, patients aged 20 to 40 years with a definitive diagnosis of KCN were participated. Only patients with the best-corrected visual acuity (BCVA) of 0.40 LogMAR or better were included. A comprehensive examination including assessment of BCVA, refractive error, and stereopsis were performed. Furthermore, all participants underwent the complementary binocular vision and accommodation testing. All examinations were performed by spectacle and then repeated after contact lens fitting in both groups.

resultsIn total, 31 patients were recruited (12 in the CRCL group and 19 in the SCL group). Both groups demonstrated significant improvements in BCVA after lens fitting in both eyes, with the SCL group showing an average gain of approximately 1-3 lines. Additionally, a higher proportion of patients in the SCL group achieved central stereopsis (<100 sec/arc) following lens fitting (p = 0.011).

conclusionsWhile both SCL and CRCL contributed to improved visual acuity in patients with KCN compared with spectacle, SCL exhibited more advantages over CRCL, particularly in enhancing stereopsis and fusional vergence performance.
