Can handheld ultrasound probes reliably measure transabdominal prostate and bladder volumes? A prospective randomized point-of-care ultrasound study.
Article in Frontiers in urology, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers, 1 of them a synthesis that pooled it.
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
Background: National guidelines recommend obtaining prostate gland volume (PGV) prior to benign prostate hyperplasia (BPH) surgery. Measurement of PGV with handheld ultrasound (HUS) probes shows promise. Objective: To compare the reliability of two HUS probes (Butterfly iQ and Clarius C3) to the BPH guideline-recommended imaging (GIm) for both prostate and bladder volumetrics. Methods: Male patients with GIm were randomized to undergo transabdominal HUS PGV with one of the two probes. A subset underwent voided volume measurements with one of the two HUS and a conventional bladder scanner (BS). The reliability of the volume measurements was assessed for each probe via intraclass correlation coefficients (ICCs). We utilized the following standard criteria: ICC < 0.5: poor reliability; 0.5 ≤ ICC < 0.75: moderate reliability; and ICC ≥ 0.75: good reliability. Results: A total of 78 men in the prostate arm (38 Butterfly, 40 Clarius) and 45 in the bladder arm (24 Butterfly, 21 Clarius) were randomized and included in this study. The mean prostate volume based on GIm was larger in the Clarius group ( Conclusions: The Butterfly iQ demonstrated good reliability for PGV and voided volume measurements, in comparison to moderate reliability for Clarius C3.
