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
purposeEvaluate short-term intraoperator reproducibility of ultrasonographic measurements of choroidal nevi using 10- and 20-MHz probes, and the efficacy of the high-frequency probes for the diagnosis of choroidal nevi.
methodsDiameters and thicknesses of choroidal nevi were measured using a 10-MHz probe and a high-frequency long focal length 20-MHz probe (Quantel Medical™). The first part of the study evaluated intraoperator reproducibility of measurements of choroidal nevi with 10- and 20-MHz probes and the second part of the study allowed the comparisons of the measurements of largest tumor diameter (LDT) of choroidal nevi of 40 patients between the 10- and 20-MHz probes. The two-way random average agreement intraclass correlation coefficients (ICC), Bland-Altman plot, and a paired t test were used.
resultsThe intraoperator reproducibility of choroidal nevi measurements with 10- and 20-MHz probes was excellent (ICC > 0.9, n = 20). Four flat nevi, not detectable at 10 MHz, could be located with the high-frequency probe (p = 0.12). There was no significant difference in thickness or LTD measurements between the 10- and 20-MHz probes (n = 31). Both techniques showed an excellent agreement (ICC > 0.8) for thickness and LTD measurements. All the choroidal nevi that were not measurable with the 10-MHz probe (n = 7) were measured with the 20-MHz probe.
conclusionThe high-frequency 20-MHz probe allows additional detection and measurements of flat choroidal nevi. When detectable, the ultrasonographic measurements of thickness and diameter of choroidal nevi are similar with both the 10- and the 20-MHz probes.
