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

backgroundAn increase in V̇O<inf>2max</inf> is important for acute myocardial infarction morbidity, and recurrence rate and intensity have been suggested as important factors in improving V̇O<inf>2max</inf>.

aimThe aim of this study was to compare the effects of maximal-intensity interval training (MIIT) and high-intensity interval training (HIIT) on exercise capacity and health-related Quality of Life (HRQoL) in patients with acute myocardial infarction (MI) at low and moderate cardiac risk in cardiac rehabilitation (CR). This study secondarily aimed to compare the effects of hospital-based phase II CR and usual care.

designThis study is a randomized controlled trial.

settingOutpatient Rehabilitation Setting. POPULATION: Fifty-nine patients with acute MI were randomly assigned to the MIIT (N.=30) or HIIT (N.=29) group, and 32 to the usual care group.

methodsTwice a week, an intervention was conducted for nine weeks in all groups. The maximum oxygen intake (V̇O<inf>2max</inf>) and MacNew Heart Disease HRQoL were evaluated before and after intervention.

resultsA significant interaction was observed between time and group for V̇O<inf>2max</inf> (P<0.001). The MIIT group showed greater improvement than those exhibited by the HIIT and usual care groups (P<0.05). Similarly, a significant time and group interaction was observed on the MacNew Global, Physical, and Emotional scales (P<0.05), but not on the social scale (P>0.05).

conclusionsCompared to HIIT and usual care, MIIT significantly increased the V̇O<inf>2max</inf> and was as safe as HIIT in patients with acute MI with low and moderate cardiac risk in CR. Additionally, MIIT and HIIT were superior to usual care in terms of improving the HRQoL. CLINICAL REHABILITATION IMPACT: Our results suggest that increased intensity in phase II CR could result in better outcomes in terms of V̇O<inf>2max</inf> increment in patients with acute MI and low and moderate cardiac risk in CR.
