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

purposePhase angle (PA), derived from bioelectrical impedance-analysis (BIA) has emerged as a reliable marker predicting clinical outcomes. This prospective observational study investigated the association between PA and a composite in-hospital outcome in major abdominal surgery.

methodsEach patient underwent BIA before surgery (PA

resultsA total of 122 adults who underwent major abdominal surgery were enrolled from July 2019 and April 2021. Twenty-three patients (53.5%) in the lower PA group (PA < 5) experienced in-hospital complications compared to 38 patients (34.2%) in the higher PA group (PA ≥ 5) (relative risk, 1.6; 95% confidence interval [CI], 1.0 to 2.4; p = 0.038).
