Comparison of ocular parameters of two biometric measurement devices in highly myopic eyes.
Article in International journal of ophthalmology, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
aimTo compare the differences and agreement of ocular biometric parameters in highly myopic eyes obtained by optical biometric measurement instruments, the OA-2000 and IOLMaster 500.
methodsTotally, 90 patients (90 eyes) were included. They were divided into high myopia group and control group. Ocular parameters, including axial length (AL), mean keratometry (Km), anterior chamber depth (ACD), and white to white (WTW), were obtained from the OA-2000 and IOLMaster 500.
resultsFor the control group, we applied Bland-Altman graphs to assess the 95% limits of agreement (LoA) for most parameters including AL, ACD, Km, and WTW (-0.24 to 0.29 mm, -0.22 to 0.45 mm, -0.39 to 0.31 D, and -0.90 to 0.86 mm, respectively). In high myopia patients, AL, ACD, Km values had wider 95% LoA (-0.34 to 0.32 mm, -0.36 to 0.34 mm, -0.57 to 0.47 D, respectively), except WTW (-0.80 to 0.68 mm). Differences were not statistically significant between these two instruments (
conclusionMost parameters obtained by the OA-2000 and IOLMaster 500 are comparable, including the AL, ACD, and K values. Among them, the agreement of the high myopia patients is poor compared to the patients without high myopia.
