Evaluating local ischemic preconditioning effects on skin perfusion using capillary refill time in healthy volunteers.
Article in Journal of clinical monitoring and computing, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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.
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
Capillary refill time (CRT) is a vaso-occlusive test that allows the non-invasive assessment of skin perfusion. A vascular occlusive test (VOT) induces transient ischemia similar to that used in preconditioning ischemia. We hypothesized that CRT could be influenced by local tissue compression mimicking ischemic preconditioning when repeated measurements are performed. In healthy volunteers (n = 30), CRTs were performed twice on the index and middle fingers of the dominant hand and the index finger of the non-dominant hand at 15-minute intervals on the first day. On the second day, two CRT measurements were taken at 30-minute intervals. No significant differences were observed in CRT measurements repeated at 15- and 30-minute intervals. Additionally, baseline CRT values did not significantly differ between the fingers of the dominant and non-dominant hands on either study day. Repeated CRT measurements are not influenced by local ischemic preconditioning in the finger over short intervals.
