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 postoperative refractive outcomes and visual quality between topography-guided laser in situ keratomileusis (TG-LASIK) and small incision lenticule extraction (SMILE) over a 6-month follow-up. Patients and Methods: This study included 100 eyes of 50 patients, 50 eyes received TG-LASIK and 50 underwent SMILE. The outcomes measured included uncorrected distance visual acuity (UDVA), spherical equivalent (SEQ), cylinder, contrast sensitivity, and objective visual quality including objective scattering index (OSI), modulation transfer function (MTF) cutoff and Strehl Ratio (SR). Results: Baseline characteristics differed between groups, with the SMILE group being younger and demonstrating better preoperative UDVA and lower cylinder. At 6 months, 98% of TG-LASIK eyes and 100% of SMILE eyes achieved UDVA of 0.0 logMAR or better, with no significant difference between groups (P = 0.315). A significantly higher percentage of eyes in the TG-LASIK group achieved SEQ within ±0.25 D (58% vs 36%, Conclusion: Both TG-LASIK and SMILE are effective and safe for myopia and astigmatism correction. TG-LASIK demonstrated higher refractive precision and better contrast sensitivity at higher spatial frequencies compared to SMILE.
