Comparison of two measurements for the lower lid margin thickness: vernier micrometer and anterior segment optical coherence tomography.

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 investigate the reliability of using anterior segment optical coherence tomography (AS-OCT) to measure the lower lid margin thickness (LLMT) from the posterior lash line to the Marx's line by comparing with a vernier micrometer.
methodsThis was a prospective, single-center, diagnostic test study. Sixty volunteers aged between 20 and 79 without ocular diseases were recruited. A vernier micrometer and AS-OCT were, respectively, used to measure the same lid margin thickness at the central lower lid.
resultsThe mean age of volunteers was 39.1 ± 13.7 years. The LLMT in 60 subjects (25 males and 35 females) measured by a vernier micrometer and AS-OCT was 1.03 ± 0.25 mm and 0.82 ± 0.21 mm, respectively. There was a significant difference between two measurements (P < 0.001). In addition, intraclass correlation coefficient (ICC) was engaged to evaluate the reliability and agreement of two measurements (ICC = 0.83). Bland-Altman plots demonstrated that 57 of 60 spots were within 95% limits of agreement. No adverse events were detected in all subjects after the measurements.
conclusionAlthough the LLMT measured by AS-OCT was less than that measured by a vernier micrometer, AS-OCT providing quantitative measurements and imaging data was also seemed to be a reliable method with a good agreement. It could be a substitute for a vernier micrometer in clinical practice in the future.
