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

unlabelledElevated C-reactive protein (CRP) is associated with an increased risk of cardiovascular disease. Physical activity has been inversely associated with CRP. However, the clinical trials examining the effect of exercise training have produced conflicting results. PURPOSE: The purpose of this study was to examine the influence an exercise training program on CRP in postmenopausal women.

methodsSedentary, overweight, or obese postmenopausal women with elevated systolic blood pressure (120-160 mm Hg; n = 464) were randomized into one of four groups: a nonexercise control or one of three aerobic exercise groups; exercise energy expenditure of 4, 8, or 12 kcal·kg(-1)·wk(-1) (KKW) for 6 months at a training intensity of 50% of peak VO2.

resultsComplete data for 421 participants were available, and mean (SD) baseline CRP was 5.7 (5.5) mg·L(-1), with no significant differences across groups. Although VO2 increased in a dose-response manner, there were no significant changes in CRP in any of the exercise intervention groups compared with the control group. Change in fitness was not associated with change in CRP, whereas change in weight was significantly associated with change in CRP.

conclusionsDespite increasing fitness, 6 months of aerobic exercise training did not improve CRP. However, improvements in CRP were associated with reductions in weight.
