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

backgroundVisceral adipose tissue (VAT) are deleterious fat deposits in the human body and can be effectively reduced by exercise intervention. Despite well-established exercise prescriptions are available, the effective dosage of exercise for reducing VAT requires verification.

objectivesThe aims of this systematic review and meta-analysis were to determine the most effective exercise dosage (modality, intensity, duration, and amount) for decreasing VAT.

methodsNine databases (EMBASE, Medline, Cochrane Central Register of Controlled Trial, PubMed, CINAHL, Scopus, Web of Science, Airiti Library, and PerioPath) were systematically searched for randomized controlled trials that objectively assessed VAT. The arms of included studies covered with different exercise modalities and dosage. Relevant databases were searched through February 2020.

resultsOf the 34 studies (n = 1962) included in systematic review, 32 (n = 1900) were pooled for pairwise or network meta-analysis. The results indicated that high-intensity interval training (SMD -0.39, 95% CI -0.60 to -0.18) and aerobic exercise (SMD -0.26, 95% CI -0.38 to -0.13) of at least moderate intensity were beneficial for reducing VAT. By contrast, resistance exercise, aerobic exercise combined with resistance exercise, and sprint interval training had no significant effects. No difference in VAT reduction was observed between exercising more or less than 150 min per week. Meta-regression revealed that the effect of VAT reduction was not significantly influenced by an increase in the duration of or amount of exercise in an exercise program. The effective dosage of exercise for reducing VAT was three times per week for 12 to 16 weeks, while duration per session for aerobic exercise was 30-60 min, and either less than 30 min or 30-60 min of high-intensity interval training accomplished sufficient energy expenditure to impact VAT.

conclusionsThese results can inform exercise prescriptions given to the general population for improving health by reducing VAT.
