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

Background: This study aimed to compare the acute and residual physiological responses elicited by three different priming exercise strategies, including high-intensity priming exercise (HIPE), low-intensity priming exercise (LIPE), and low-intensity priming exercise with blood flow restriction (LIPE-BFR), on oxygen uptake kinetics, muscle oxygenation, and metabolic load during severe-intensity cycling in trained anaerobic athletes. Methods: Sixteen trained anaerobic athletes completed a randomized crossover protocol with three priming conditions (HIPE, LIPE, and LIPE-BFR) in a randomized order. The experimental protocol began with an incremental exercise test to determine maximal oxygen uptake (VO Results: Compared with HIPE, both LIPE and LIPE-BFR induced significantly lower amplitude (A) and longer time delay (TD), along with reduced reduced minimum SmO Conclusion: Although the three priming strategies elicited distinct acute physiological responses, their residual effects on oxygen uptake kinetics and metabolic outcomes during subsequent severe-intensity exercise were largely comparable. Future studies should further explore alternative priming protocols and refine experimental designs to better clarify the effects of priming.
