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

aimTo analyze the two-year visual and refractive outcomes as well as the safety, and efficacy of photorefractive keratectomy (PRK) surgery for myopia.

methodsIn this prospective cohort study, 63 eligible patients were recruited, including 45 women (71.4%) and 18 men (28.6%). Demographic characteristics along with pre- and post-operative clinical data including visual acuity, refraction, maximum ablation, spherical and cylindrical error, and residual stromal bed (RSB) were evaluated.

resultsThe mean age of the patients was 35.42±8.16y (range 22 to 55y). The mean spherical and cylindrical error before surgery were -2.23±1.58 D (range -5 to +0.25) and -1.24±0.94 D, respectively (range -3.75 to 0.00). The mean efficacy and safety of PRK surgery at 2y follow-up were 0.98±0.06 and 1.01±0.04 respectively. The lower age was significantly correlated with a higher amount of efficacy index (

conclusionThe two-year efficacy and safety of PRK for the treatment of low myopia is excellent. Younger age and lower amount of refractive error are correlated with higher efficacy and safety indices of the surgery.
