Automated body weight measurement using computed tomography.

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
Computed tomography (CT) images provide detailed information on tissue composition and density. Body weight estimation from CT can be highly relevant in emergency and forensic contexts where conventional weighing is impractical or unavailable-for example, due to unconscious or immobilized patients, lack of appropriate equipment, or the necessity to preserve forensic trace evidence. An automated method for body weight estimation using antemortem and postmortem CT data from clinical scanners was evaluated. Two retrospective cohorts were included: 30 forensic postmortem whole-body CT scans and 66 clinical torso CT scans. Tissue segmentation applied predefined Hounsfield Unit thresholds for fat, muscle, and bone, with voxel volumes multiplied by corresponding tissue densities to calculate weight. In forensic cases, CT-derived weights differed by - 1.26 ± 2.58 kg (median: - 1.15 kg) from measured weights. In clinical cases, torso weight was extrapolated to total body weight using a corrected scaling factor that accounted for body and scan length, resulting in an average difference of 0.53 ± 4.62 kg (median: 0.23 kg). Linear regression demonstrated strong correlations (R
