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

Introduction: Preoperative chemoradiotherapy (CRT) for rectal cancer may have an attritional impact on body composition and functional status, affecting postoperative outcomes. This prospective study characterized changes in body composition, muscle strength, and physical performance in patients with rectal cancer receiving CRT. Methods: Body composition measures by a bioelectrical impedance analysis, hand grip strength (HGS), gait speed, and the nutritional status by the Mini-Nutritional Assessment (MNA) were assessed at Weeks 0 (pre-CRT), 2, 4, 6, and 10 (post-CRT). The pre-sarcopenic status was defined as low muscle mass alone and the sarcopenic status as low muscle mass and low muscle strength or function. Results: The median age of 38 enrolled patients (25 men) was 59 years. The mean body fat mass, phase angle, and non-dominant HGS significantly decreased by 1.3 kg, 0.3°, and 0.7 kg, respectively, after CRT. Skeletal muscle mass and the MNA slightly decreased, while gait speed did not change. Significant reductions were observed in body fat mass (2.3 kg, Conclusion: Muscle strength and body fat decreased in patients receiving CRT, particularly women. These exploratory data provide a foundation for future investigations into the clinical utility of sex-sensitive therapeutic approaches.
