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

backgroundThe etiology of pain in chronic pancreatitis is multi-factorial and includes altered central pain processing. Pancreatic Quantitative Sensory Testing (P-QST) indirectly assesses pain sensitization, yet its clinical significance in relation to psychological comorbidities and quality of life (QoL) remains unclear in Indian populations. The primary objective was to apply an unbiased, data-driven clustering approach using P-QST parameters to stratify patients into centrally sensitized and non-sensitized phenotypes and evaluate their associations with demographic, clinical and patient-reported outcome variables.

methodsThis cross-sectional study enrolled Indian patients with painful chronic pancreatitis between June 2021 and October 2023. We assessed static (pressure pain thresholds and cold pressor endurance) and dynamic (temporal summation and conditioned pain modulation) P-QST parameters to characterize pain processing. Psychological comorbidities, pain catastrophizing and quality of life were measured using validated questionnaires. We compared demographic, clinical and patient-reported outcome variables across pain phenotypes identified from K-median clustering of P-QST parameters.

resultsWe enrolled 264 patients (mean [SD] age- 35.6 [11.0] years, male [%]- 177 [67], idiopathic etiology [%]- 188 [71]). Cluster analysis revealed two distinct pain phenotypes: sensitized (n = 100) and non-sensitized (n = 164). Sensitized patients had lower pressure detection thresholds (2020 vs. 2691 kPa; p < 0.001), shorter cold pressor endurance time (40 s vs. 70 s; p < 0.001) and greater temporal summation (p < 0.001). Demographics and clinical characteristics were comparable between groups, but sensitized patients reported poorer physical (p = 0.037) and social functioning (p = 0.027) and greater fatigue (p = 0.012). No differences were observed for psychological comorbidities.

conclusionUsing an unbiased, data-driven approach, we identified distinct P-QST pain phenotypes in chronic pancreatitis patients, independent of psychological comorbidities, supporting its potential as an unbiased pain assessment tool.
