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.
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 effects of applied suction using microkeratome Laser-assisted in situ keratomileusis. (LASIK), femtosecond-laser in-situ keratomileusis (Fs-LASIK), and Small Incision Lenticule Extraction (Fe-SMILE) on the thickness of the Retinal Nerve Fiber Layer (RNFL) and Ganglion Cell Layer (GCL). Patients and Methods: This study included 72 eyes divided into three groups, each with 24 eyes. Each group underwent one of three different procedures. Preoperatively, at one day, one week, and three months postoperatively, Spectral Domain Optical Coherence Tomography (SD-OCT) was used to evaluate the thickness of RNFL and GCL. Results: Preoperatively and at one day, one week, and three months postoperatively, the mean values for RNFL thickness in the LASIK group were 93.2 ± 3.2, 105.9 ± 3.8, 106.2 ± 3.3, and 93.3 ± 3.6 μm, respectively; for the Fs-LASIK group, they were 95.9 ± 3.1, 100.2 ± 3.3, 100.5 ± 3.3, and 96.1 ± 3.1 μm, respectively; and for the Fe-SMILE group, they were 95.6 ± 1.9, 99.8 ± 1.7, 100.2 ± 1.8, and 95.8 ± 1.9 μm, respectively. The mean values for GCL thickness in the LASIK group were 73.9 ± 4.7, 90.2 ± 2.8, 90.8 ± 2.2, and 74.8 ± 4.5 μm, respectively; for the Fs-LASIK group, they were 77.8 ± 4.2, 80.2 ± 3.7, 80.3 ± 3.7, and 77.8 ± 3.5 μm, respectively; and for the Fe-SMILE group, they were 77.0 ± 3.7, 79.8 ± 3.6, 80 ± 3.7, and 77.1 ± 3.6 μm, respectively. Conclusion: All three procedures resulted in a transient increase in RNFL and GCL thicknesses. This increase was rapid, limited, transient, and reversible. It peaked for a week and returned to baseline by the end of this three-month study. At day one and day seven post-operatively, the Lasik group exhibited statistically significantly higher values than the Fs-Lasik and Fe-Smile groups.
