The Association of Pain Phenotype with Neuromuscular Impairments and Mobility Limitations Among Older Primary Care Patients: A Secondary Analysis of the Boston Rehabilitative Impairment Study of the Elderly.
Article in PM & R : the journal of injury, function, and rehabilitation, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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.
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
backgroundClarifying the relationship between pain phenotypes and physical function in older adults may enhance screening and treatment for functional decline in primary care settings.
objectiveTo investigate the association of more severe pain phenotypes with neuromuscular impairments or mobility limitations among older community-dwelling primary care patients.
designCross-sectional analysis.
settingThe Boston Rehabilitative Impairment Study of the Elderly.
participantsAdults aged 65 years or older.
methodsWe counted the number of musculoskeletal pain locations (none, single site, multisite, or widespread) using the McGill Pain Questionnaire and identified pain intensity tertiles using the Brief Pain Inventory. Neuromuscular attributes (trunk extensor muscle endurance, and leg speed, strength, strength asymmetry, and range of motion) and mobility (Short Physical Performance Battery [SPPB]) were assessed with performance-based measures. Additionally, self-reported mobility was measured on the Late Life Function and Disability Instrument (LLFDI). For neuromuscular attributes and LLFDI, scores in the lowest tertile indicated neuromuscular impairment or mobility limitations, respectively. For SPPB, a score <7 (of 12) indicated severe mobility limitations.
resultsAmong 430 participants (mean age = 77) most were female (68%), white (83%), and had either multisite (50%) or widespread (14%) pain. After adjusting for baseline characteristics, widespread pain (compared to none) was associated with slow leg speed (adjusted odds ratio, 95% confidence interval: aOR = 2.33, 1.03-5.27), limited ankle range of motion (aOR = 2.15, 1.03-4.47) and mobility limitations on LLFDI (aOR = 3.85, 1.81-8.19). Being in the highest pain intensity tertile, versus lowest tertile, was associated with poor trunk extensor muscle endurance (aOR = 2.49, 1.41-4.39), limited ankle range of motion (aOR = 2.15, 1.25-3.71), and mobility limitations on SPPB (aOR = 2.56, 1.45-4.52), and LLFDI (aOR = 4.70, 2.63-8.40).
conclusionsAmong ambulatory, older primary care patients, more severe pain phenotypes are associated with neuromuscular impairments identified on physical testing and mobility limitations on validated measures.
