A Self-Reported Electronic Body Map Identifies Distinct Clinical Pain Phenotypes in Chronic Pancreatitis.

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
introductionSome patients with chronic pancreatitis (CP) experience nociplastic pain due to central nervous system dysregulation, yet its recognition is limited by the lack of bedside tools. Self-reported body maps are used to assess pain widespreadedness and to differentiate pain mechanisms in chronic pain patients, but their utility in CP is unclear. This study aimed to determine whether pain widespreadedness, measured through a body map, is associated with features of nociplastic pain in CP.
methodsWe conducted a cross-sectional analysis of adults with definite CP enrolled in a single-center longitudinal cohort. Pain widespreadedness was assessed using the Michigan Body Map and categorized by the number of painful regions (0-7) and by the presence of localized vs widespread (≥3 regions) pain. Clinical features of nociplastic pain were measured using validated psychometric and pain surveys. Group comparisons were performed with multivariable regression models adjusted for demographics, comorbidities, and CP characteristics.
resultsAmong 110 participants (mean age 54 years, 52% male), 93% reported abdominal pain. Of those with abdominal pain, 64% had widespread pain. Increasing the number of painful regions and widespread pain (vs localized) were independently associated with higher pain severity, pain interference, and neuropathic pain scores, as well as more fatigue, impaired physical functioning, greater chronic overlapping pain conditions, and poorer physical and mental health. DISCUSSION: Two-thirds of patients with CP had widespread pain assessed using a body map. This subgroup had more severe symptoms and features of nociplastic pain. This simple tool may facilitate targeted, mechanism-based pain management in CP.
