Intra- and inter-rater reliability of urethral mobility measurement by ultrasound in women: a cross-section study.
Article in International urogynecology journal, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
introduction and hypothesisTo verify the intra- and inter-rater reliability of urethral mobility measurement evaluated by ultrasound (US).
methodsThis is a reliability study realized according to Consensus-based Standards for the selection of health Measurement Instruments (COSMIN) recommendations. Twenty-one nulliparous women (25.5 ± 3.3 SD years) were volunteers. Two examiners (E1 and E2) performed the measurement of urethral mobility at rest and Valsalva on the same day. Three measurements were recorded for each moment and the mean of them were used for analysis. To perform the analysis, bladder mobility was calculated using the following equation: [Formula: see text], where "x" is the vertical distance, "y" is the horizontal distance from the dorsocaudal margin of the pubic symphysis, "V" is the Valsalva maneuver, and "R" means rest. The intraclass correlation coefficient (ICC) was calculated considering: ICC ≥ 0.75, excellent; 0.40 ≤ ICC <0.75, satisfactory; ICC < 0.40, poor, with a significance level of 5% and 95% confidence interval.
resultsThe intra-rater reliabilities of E1 and E2 were considered excellent between the two evaluations, with ICC 0.98 (p < 0.0001) for the E1 and 0.84 (p < 0.0001) for E2. The inter-rater reliability was considered excellent (ICC = 0.83).
conclusionsBoth intra- and inter-rater reliabilities of urethral mobility measurement were considered to have excellent agreement.
