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 compare the safety, efficacy and changes in corneal aberrations between Implantable Collamer Lens (ICL) combined with Limbal Relaxing Incision (LRI) and Toric ICL (TICL) implantation for moderate astigmatism (1.00-1.75 D). Methods: A retrospective study included 30 subjects (46 eyes) assigned to ICL combined with LRI (23 eyes) or TICL (23 eyes) group. Uncorrected distance visual acuity (UDVA), objective refraction, astigmatism vector analysis were assessed preoperatively and at 1 week, 1 month and 3 months postoperatively; corneal aberrations were compared preoperatively and 3 months postoperatively. Results: Both groups showed comparable outcomes in visual acuity, refraction postoperatively. Surgically Induced Astigmatism (SIA) showed a decreasing trend in the LRI group (1.07 to 0.92, P = 0.044), while it remained stable in the TICL group (1.11 to 1.20, P = 0.507). Total corneal wavefront aberrations, spherical aberration and horizontal coma postoperatively showed reduction in LRI group, whereas slightly increased in the TICL group (all P< 0.05). Conclusion: Both ICL combined with LRI and TICL implantation achieve good efficacy in correcting moderate astigmatism. The TICL group showed better postoperative astigmatism stability. The LRI group demonstrated reductions in several corneal aberration parameters compared with the TICL group.
