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

purposeAttenuation techniques have been developed to quantify liver fat, improving diagnostic accuracy. However, the standardization of measurement methods remains undefined, limiting clinical application. This study evaluated the effect of different region of interest (ROI) settings on the attenuation coefficient (AC) and coefficient of determination (R

methodsWe analyzed 5212 ultrasound examinations performed at our institution. Two periods were compared: early [ROI positioned at twice the subcutaneous thickness; double positioning (DP), 2 × 3 cm] and late [ROI placed beneath the multireflection layer; color positioning (CP), 2 × 4 cm]. Additionally, AC and R

resultsThe early and late periods included 2881 and 2331 examinations, respectively. Patient characteristics were comparable. Significant differences were observed in the AC (median, 0.58 vs. 0.56 dB/cm/MHz), steatotic liver diagnostic rates based on AC, R

conclusionIn ATI, the larger ROI improved R
