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
This study aimed to analyze and compare the effects of intraoperative delayed time (IDT) on refractive correction accuracy in femtosecond laser-assisted stromal in situ keratomileusis (FS-LASIK) using 1050 Hz excimer laser equipment. Eighty-one eyes of 81 myopic and astigmatic patients were divided into three groups according to the IDT: mild delay (IDT < 5 s, 29 eyes), moderate delay (5 s ≤ IDT < 10 s, 26 eyes), and severe delay (10 s ≤ IDT ≤ 60 s, 26 eyes) groups. Uncorrected distance visual acuity (UDVA), spherical equivalent (SE), and intraocular pressure (IOP) were measured 1 week, 1 month, and 3 months postoperatively. The static cyclotorsion and dynamic cyclotorsion components (SCC and DCC, respectively) were recorded. Central corneal thickness was measured before and 1 week after the operation. Differences in the UDVA, refractive power correction error (RPCE), and corneal ablation error (CAE) between the different groups were compared. The postoperative UDVA of the three groups was good; no significant difference as observed in the SCC and RPCE 1 week after surgery. The DCC and RPCE at 1 and 3 months postoperatively in the three groups significantly varied. For patients with an IDT less than 10 s, no significant difference was observed between the actual and theoretical ablation corneal thicknesses. However, for those with IDT longer than 10 s, the actual ablation thickness was greater than the theoretical ablation thickness. The CAE increased with the IDT lengthening, and the average actual ablation depth increased by 0.09 μm for every extra second. Education and training on preoperative ocular fixation should be emphasized. Patient delay in laser ablation due to poor cooperation may still lead to RPCE and CAE, even though the 1050 Hz excimer laser has the highest ablation speed, highest tracking speed, and seven-dimensional eye movement tracking.
