1 · What the graph read from 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.

2 · The registry

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

backgroundAccurate liver volume measurement is crucial for evaluating liver cyst severity and treatment efficacy in polycystic liver disease (PLD). Previous methods are impractical because they are time-consuming and labor-intensive. This study developed and validated two simplified CT imaging methods: the Bi-axial Simplified Measurement Method (BASiM) and the Quadri-dimensional Simplified Measurement Method (QDSiM).

methodsThis retrospective study analyzed 76 CT images from 26 PLD patients who underwent transarterial hepatic artery embolization (TAE). Images were obtained before TAE, 24 weeks after TAE and during the follow-up period. Liver volumes were measured using semi-automatic volumetry, BASiM, and QDSiM. BASiM calculates liver volume based on cranio-caudal, anterior-posterior, and medial-lateral dimensions, while QDSiM divides the liver into left- and right-side sections. This study assessed inter-assessor reliability, measurement accuracy, volume change rate, and calculation times.

resultsBASiM demonstrated strong inter-assessor reliability (intraclass correlation coefficient [ICC]: 0.991, 95% confidence interval [CI] 0.986-0.994) superior to QDSiM (ICC: 0.851, 95% CI 0.205-0.949). Calibrated liver volumes using BASiM and QDSiM were consistent with semi-automatic volumetry (ICC: 0.924, 95% CI 0.858 to 0.957, and ICC: 0.934, 95% CI 0.806-0.970, respectively). BASiM showed better alignment with volume changes (ICC: 0.835, 95% CI 0.537-0.927) compared to QDSiM (ICC: 0.607, 95% CI 0.203-0.800) and required less measurement time (61 ± 4 s vs. 107 ± 9 s, p < 0.01).

conclusionBASiM provided superior reliability, accuracy, and efficiency for liver volume measurement in PLD, thus useful for the clinical management of PLD.
