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

purposeThis study aimed to test whether equivalent changes in moderate (walking) and vigorous exercise (running) produce equivalent weight loss under free-living, nonexperimental conditions.

methodsRegression analyses of changes (Δ) in body mass index (BMI) versus exercise energy expenditure (ΔMET-hours per day, 1 MET = 3.5 mL O2·kg·min) from survey questionnaires completed at baseline and 6.2 yr thereafter in 15,237 walkers and 32,216 runners were used in this study.

resultsAt baseline, walkers spent less energy walking than runners spent running (mean ± SD; males = 2.22 ± 1.65 vs 5.31 ± 3.12 MET·h·d, females = 2.15 ± 1.63 vs 4.76 ± 3.03 MET·h·d), and walkers were significantly heavier than runners (males = 26.63 ± 4.04 vs 24.09 ± 2.58 kg·m, females = 25.44 ± 5.14 vs 21.61 ± 2.49 kg·m). During follow-up, energy expenditure declined less for walking in walkers than for running in runners (males = -0.19 ± 1.92 vs -1.27 ± 2.87 MET·h·d, females = -0.30 ± 1.93 vs -1.28 ± 2.85 MET·h·d). ΔBMI was inversely related to both ΔMET-hours per day run and ΔMET-hours per day walked, but more strongly to ΔMET-hours per day run than walked in men and in heavier women. Specifically, the regression coefficient for ΔBMI versus ΔMET-hours per day was significantly more negative for running than walking in men in the first quartile (differences in slope ± SE: -0.06 ± 0.03, P = 0.01), second quartile (-0.10 ± 0.03, P = 0.001), third quartile (-0.17 ± 0.03, P < 10), and fourth quartile of BMI (-0.14 ± 0.03, P < 10) and in the fourth BMI quartile of women (-0.32 ± 0.04 kg·m per MET-hours per day, P < 10). This represented 90% greater weight loss per MET-hours per day run than walked in the fourth BMI quartile for both sexes. Age-related weight gain was attenuated by running in both sexes (P < 10) and by walking in women (P = 0.005).

conclusionAlthough ΔBMI was significantly associated with both ΔMET-hours per day run and walked, the ΔBMI was significantly greater for Δrunning than Δwalking.
