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

purposeThis study investigated changes in pupil deviation after cataract surgery. STUDY

designSingle-center, retrospective observational study.

methodsThis single-center, retrospective observational study included 102 patients (204 eyes). Measurements were performed preoperatively and 1 month postoperatively using an optical interference axial length-measuring device. Pupil diameter, as well as the relative positions of the corneal center, pupil center, and visual axis, were analyzed.

resultsCompared with the preoperative measurements, the average pupil diameter of the right eye changed significantly (3.252 ± 0.518 mm vs. 3.029 ± 0.490 mm; p < 0.01), while the horizontal deviation of the visual axis relative to the corneal center did not (0.337 ± 0.152 mm vs. 0.321 ± 0.154 mm). The position of the pupil center relative to the corneal center shifted nasally by 0.220 ± 0.111 mm preoperatively and 0.298 ± 0.120 mm postoperatively. Additionally, the visual axis relative to the pupil center shifted significantly, from 0.117 ± 0.162 mm preoperatively to 0.023 ± 0.144 mm postoperatively (p < 0.01). This indicated that the pupil center moved nasally. The left eyes displayed tendencies consistent with those observed in the right eyes.

conclusionAfter cataract surgery, the pupil center shifted nasally and moved closer to the visual axis, whereas the position of the corneal center relative to the visual axis remained essentially unchanged.
