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

purposeTo compare short-term corneal epithelial thickness changes measured by optical coherence tomography (OCT) in eyes fitted with two different silicone hydrogel bandage contact lenses (BCL) following trans-epithelial photorefractive keratectomy (t-PRK).

methodsIn this prospective contralateral-eye study, 60 eyes of 30 patients with myopia without astigmatism underwent t-PRK using WaveLight EX500 excimer laser. Balafilcon A was applied to one eye and senofilcon A to the fellow eye in a randomized manner. All BCLs were removed on postoperative day 5. Corneal epithelial thickness was assessed preoperatively and on postoperative days 5, 15, and 30 using spectral-domain optical coherence tomography (REVO FC). Measurements were obtained centrally and across eight mid-peripheral quadrants. Epithelial thickness and spherical equivalent (SE) were compared.

resultsThe mean age of the participants was 27.11 ± 6.80 years. Preoperatively, no significant differences were observed between the groups in SE (- 2.93 ± 1.11 D vs. - 2.71 ± 1.44 D; p = 0.353), ablation depth, central corneal thickness, or epithelial thickness. On postoperative day 5, slightly higher epithelial thickness values were observed in the nasal, temporal, and superotemporal quadrants in the balafilcon A group in unadjusted analyses; however, these differences did not remain statistically significant after false discovery rate correction. No significant differences were observed between the other regions. By postoperative days 15 and 30, epithelial thickness was comparable across all quadrants. At 1 month, the SE values were similar (p = 0.302), although balafilcon A showed a trend toward values closer to emmetropia.

conclusionsBoth bandage contact lens materials demonstrated broadly comparable short-term postoperative epithelial remodeling patterns and refractive outcomes after t-PRK. Minor early regional differences observed on OCT should be interpreted cautiously.
