Characterizing Extreme Phenotypes for Pain Catastrophizing in Persons With Chronic Pain Following Mild to Severe Traumatic Brain Injury Requiring Inpatient Rehabilitation: A NIDILRR and VA TBI Model Systems Collaborative Project.
Article in The Journal of head trauma rehabilitation. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
objectiveDefine and characterize extreme phenotypes of pain catastrophizing for persons with chronic pain following mild to severe traumatic brain injury (TBI) requiring inpatient rehabilitation.
setting18 TBI Model System (TBIMS) centers.
participants1762 TBIMS participants 1 to 30 years post-injury reporting chronic pain.
designCross-sectional, secondary analyses. PRIMARY MEASURES: Catastrophizing, sociodemographic, injury, functional outcome, pain, and treatment characteristics.
resultsParticipants were male predominantly (73%), White (76%), middle-aged (mean 46.5 years), injured in motor vehicle accidents (53%) or falls (20%). Extreme phenotypes were identified based on upper and lower 25 th percentiles to create low catastrophizing (N = 434) and high catastrophizing (N = 458) groups. Bivariate comparisons found significant differences ( P < .001) on all measures of concurrent function and pain interference with those in the low catastrophizing phenotype experiencing better function and lower pain interference than those in the high catastrophizing phenotype. Combination Lasso and logistic regression identified multivariable predictors of phenotypes. Increased odds of high versus low catastrophizing extreme phenotypes were associated being younger (odds ratio [OR] = 1.24 for a 10-unit decrease), less than a college level of education (OR = 1.70-2.53), no military history (OR = 3.25), lower FIM motor (OR = 1.20 for a 5-unit decrease) and cognitive (OR = 1.53 for a 5-unit decrease) scores, increased pain intensity (OR = 1.22 for a 1 unit increase) and pain interference (OR = 1.93 for a 1-unit increase), neuropathic type pain (OR = 1.82-1.86), and migraine type pain versus no head pain (OR = 1.65).
conclusionHigh pain catastrophizing phenotypes were associated with a greater degree of pain and functional disability and higher likelihood of neuropathic pain and migraine headache. Given pain catastrophizing's contribution to pain-related disability and treatment outcomes, additional research is necessary to investigate its role in adjustment to chronic pain among individuals with TBI. Adapting evidence-based interventions for this population that specifically targets pain catastrophizing is warranted.
