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

backgroundBecause obesity is an independent risk factor for breast cancer recurrence, assessment of body composition is crucial to guide weight management in breast cancer survivors (BCS). This study assessed whether dual-energy x-ray absorptiometry (DXA) and bioelectrical impedance analysis (BIA) yield similar results for body composition in BCS.

methodsBody fat percentage, lean body mass, and fat mass were estimated using DXA and BIA under fasting conditions in 89 BCS. BMI categories included normal (18-24.99 kg/m

resultsThere was no agreement between the 2 devices for body fat percentage (DXA: 44.2 ± 6.2% vs BIA: 40.4 ± 7.8%), lean body mass (DXA: 39.1 ± 7.6 kg vs BIA: 42.9 ± 5.9 kg), and fat mass (DXA: 32.4 ± 10.8 kg vs BIA: 30.6 ± 11.0 kg; P < .001). These findings were consistent in normal, overweight, and obese BCS. There was agreement between the 2 devices for fat mass (DXA: 48.7 ± 7.2 kg vs BIA: 47.9 ± 5.7 kg) in severely obese BCS (P = .102), possibly due to small sample size.

conclusionsBIA may underestimate body fat percentage and fat mass and overestimate lean body mass, compared with DXA. Future studies are warranted to assess the use of these 2 devices in a larger cohort of BCS within BMI categories.
