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

backgroundRegular activity breaks improve postprandial glycemia, but the effects across different population groups and modes of breaks remain unclear. This systematic review and meta-analysis examined the impact of activity breaks on postprandial glucose and insulin response in adult populations.

methodsStudies were identified from five databases until October 9, 2024. Eligible studies were acute (< 24-h duration) laboratory-based randomized crossover trials comparing postprandial glucose and/or insulin response between prolonged sitting and activity breaks (< 10 min, ≥ 3 breaks over 3 h). Risk of bias was assessed using the Downs and Black quality assessment tool. Random-effects meta-analysis was conducted including subgroup analyses by activity mode, frequency, and participant health/weight status.

resultsOverall 53 studies met the eligibility criteria; 39 were included in the meta-analysis. Compared with prolonged sitting, activity breaks lowered postprandial glucose incremental area under the curve (iAUC) (SMD -0.30, 95% CI -0.43 to -0.13) and insulin iAUC (SMD -0.30, 95% CI -0.46 to -0.14). Walking breaks had the greatest effect on glucose iAUC (SMD -0.33, 95% CI -0.48 to -0.17) and insulin iAUC (SMD -0.44, 95% CI -0.62 to -0.27), compared with other modes. Interrupting sitting every 15-20 min produced the largest reductions in glucose (SMD -0.51, 95% CI -0.83 to -0.19) and insulin iAUC (SMD -0.41, 95% CI -0.77 to -0.06). The largest reduction in glucose iAUC was observed in those living with obesity (SMD -0.52, 95% CI -1.07 to 0.03).

conclusionFrequent short walking breaks, performed every 20 min, provide the most improvement in postprandial glucose and insulin response in adults.
