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

purposeAnalysis of different corneal parameters in patients seeking corneal refractive surgery.

methodsPatients examined by Oculus Pentacam

resultsThe study included 5059 eyes of 2694 subjects; the mean age was 27.46 ± 7.04 (18-45) years, and most of them were of female gender, representing 1886 subjects (70.007%). The mean spherical equivalent was - 2.94 ± 3.68 diopters. The most common topographic shape was a symmetric bow tie in 2474 eyes (48.9%). Abnormal back elevation was reported in 19.4% of studied eyes and keratoconus in 4.1% of the studied eyes.

conclusionExamination of refractive surgery candidates revealed that high myopia is frequent, the most frequent topographic shape is the symmetric bowtie, and keratoconus is infrequent, but abnormal back elevation had a higher percentage. Therefore, routine corneal examination by pentacam is recommended for these patients regardless of whether they are seeking refractive surgery or not. Our findings emphasize the importance of conservative pachymetry thresholds (≥500 µ) in regions with higher keratoconus risk. Future research should focus on longitudinal tracking of refractive surgery candidates to better understand the impact of subclinical ectasia markers on long-term outcomes.
