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

Objective: To examine how acupuncture at Shousanli (LI10) influences blood oxygen metabolism in tissues beneath acupoints along the Hand-Yangming Large Intestine Meridian, as well as at non-meridian sites, with the aim of validating acupoint specificity and meridian transmission. Methods: 60 healthy volunteers were randomized to acupoint (n=30, LI10) or non-meridian (n=30, 2 cm medial to LI10) groups. Photoacoustic imaging assessed oxygen saturation (SO Results: Following acupuncture at LI10, local SO Conclusion: Acupuncture at Shousanli can specifically regulate blood oxygen metabolism at acupoint regions and demonstrates meridian-oriented transmission characteristics, providing visualized evidence for acupoint specificity.
