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

Purpose: To investigate the efficacy of image-guided accurate limbal relaxing incisions (LRIs) for astigmatism correction during cataract surgery. Methods: Consecutive cataract patients with regular corneal astigmatism ranging from 0.75 to 2.50 D, intended for cataract surgery with image-guided LRIs, were recruited in this prospective cohort study. The efficacy of astigmatism correction was evaluated 3 months after surgery, and compared among eyes with preoperative corneal with-the-rule (WTR), against-the-rule (ATR) and oblique astigmatism. Higher-order aberrations and visual quality indices obtained with iTrace were further compared between eyes with single and paired LRIs. Results: Totally, 108 eyes of 108 patients were analyzed. The mean total surgical induced astigmatism (tSIA) vector of all participants was 0.76 ​± ​0.38 D (range: 0.11-1.79 D, preoperative vs. postoperative astigmatism: 1.46 ​± ​0.41 vs. 0.78 ​± ​0.44 D, Conclusions: Image-guided LRIs can effectively correct low-to-moderate corneal astigmatism during cataract surgery, especially in eyes with WTR astigmatism.
