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

introductionMenopause is accompanied by decreased aerobic fitness and increased risk of cardiovascular disease. Sprint interval training (SIT) is a time-efficient intervention for improving cardiovascular function and aerobic fitness of young adults.

aimTo determine the effect of an 8-week SIT program on the cardiovascular function and aerobic fitness of overweight postmenopausal women.

methodThirty overweight postmenopausal women were randomized into exercise (n = 15) or control (n = 15) groups. The intervention group completed three SIT sessions a week for 8 weeks. Each session consisted of 20 min of 8-s sprints and 12 s of light pedalling. Participants also completed 8 min of light aerobic cycle exercise, before and after the SIT intervention. Cardiovascular function including heart rate, stroke volume (SV), and diastolic filling time (DFT) was assessed before and after the intervention and during 8 min of light aerobic exercise. Estimated maximal oxygen uptake ([Formula: see text]) was also assessed.

resultsResting SV was increased (p = 0.001) from pre- (77.5 ± 17.0 mL) to post-SIT (81.3 ± 17.0 mL), whereas SV during 8 min of light aerobic exercise was increased (p = 0.000), from pre- (97.8 ± 1.6 mL) to post-test (103.5 ± 17.8 mL). Resting DFT was increased, (p = 0.010), at pre- (333.4 ± 94.4 mL) to post-SIT (357.4 ± 88.2 mL), whereas DFT during 8 min of aerobic exercise was increased, (p = 0.000), from pre- (480.1 ± 99.5 mL) to posttest (527.2 ± 123.0 mL). Predicted [Formula: see text] was increased, (p = 0.016), from pre- (19.5 ± 5.87 mL kg

conclusionSIT improved cardiovascular function and aerobic fitness of overweight postmenopausal women after 8 weeks of exercise.
