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
purposeTo assess the repeatability of measuring the corneal diameter (white-to-white, WTW) using Sirius and IOLMaster 700 in myopic eyes, to evaluate their consistency and relationship with sulcus-to-sulcus (STS) and angle-to-angle (ATA).
methodsThis retrospective study enrolled 58 volunteers with myopia (116 eyes). Each subject was evaluated using Sirius, IOLMaster 700 and ultrasound biomicroscope (UBM) for parameters which included WTW, STS, and ATA. STS referred to horizontal STS (STS
resultsThree repeated measurements of WTW by Sirius and IOLMaster 700 showed no statistically significant discrepancies between the data (F = 0.306; 2.469, P > 0.05), and the difference between the data of paired t-tests of the mean values of WTW measured by each instrument was statistically significant (t= -2.894, P < 0.01). The Sw, precision, repeatability, CoV, ICC, CoA values for WTW measured by Sirius and IOLMaster 700 were (0.027, 0.054, 0.076, 0.232%, 0.981, 0.993) and (0.079, 0.155, 0.219, 0.666%, 0.980, 0.993), respectively. This trial demonstrated by Bland-Altman plots that the 95% LoA (Limits of agreement) for concordance between WTW measured by Sirius (WTW
conclusionThe repeatability of WTW measured by Sirius and IOLMaster 700 was satisfactory. The WTW measured by IOLMaster 700 was bigger than the WTW measured by Sirius. The parameters of WTW
