Impact of repeated exposure to CPM on CPM efficiency and pain sensitivity in healthy adults: a randomized controlled trial.
Trial report in Frontiers in pain research (Lausanne, Switzerland), 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT05783362 (Pain Modulation Effectiveness), which is not on this map. Cited by 3 papers.
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.

Abstract
Conditioned pain modulation (CPM) is a behavioral measure of diffuse noxious inhibitory control (DNIC), an endogenous central pain modulatory mechanism in which one pain stimulus suppresses the perception of another. CPM efficiency is reduced in individuals with chronic pain and serves as a potential predictor for the development of chronic pain conditions. Current research indicates that CPM, traditionally viewed as a static metric, may exhibit protocol-dependent variability in its effects on pain sensitivity, potentially through neuroplastic mechanisms and central pain processing pathways. This randomized controlled trial (NCT05783362) investigated whether repeated activation of central pain modulatory systems enhances CPM efficiency. The secondary aim examined associations between repeated CPM exposure and pain-related psychological factors. Sixty healthy participants (52% female; ages 18-75) were randomly allocated to High Exposure (HE), Low Exposure (LE), or No Exposure (NE) CPM intervention groups. Pre- and post-intervention measures included CPM efficiency and pain sensitivity across thermal and pressure pain tests. Two-way ANOVA analyses revealed significant main effects for both time ( Clinical Trial Registration: https://clinicaltrials.gov/study/NCT05783362, identifier NCT05783362.
