Sex Differences in Experiencing and Reporting Low Back Pain Using Standardised Questionnaires: A Cross-Sectional Study.
Observational study in Musculoskeletal care, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundChronic low back pain (CLBP) is one of the leading causes of disability. Evidence suggests that women experience and report pain differently than men, showing lower thresholds, greater intensity, and higher frequency of pain reports. Understanding these differences is crucial for the interpretation of standardized questionnaires. The aim of the study was to investigate sex differences in the descriptors of the McGill Pain Questionnaire (MPQ) chosen by men and women with CLBP and their relationship with pain intensity.
methodsThis is a descriptive, cross-sectional, and observational study. Men and women with nonspecific CLBP aged 18-80 years and numerical pain rating scale (NPRS) > 1, were recruited. Participants completed sociodemographic forms, NPRS and the MPQ.
resultsThe study assessed 310 participants (women: n = 201, 64.8%; men: n = 109, 35.2%). Out of the 20 subcategories analysed, five showed a difference in the prevalence of words between sexes (subcategories 1, 5, 6, 9, and 11). The most frequently selected words of the MPQ, with over 80% of responses, were 'crushing', 'aching', 'tiring', 'tight', and 'cool'. A correlation was found between NPRS and total PRI, sensory PRI, and miscellaneous PRI were observed only in women (p < 0.05, r > 0.3).
conclusionThis study reinforces the importance of considering sex when interpreting standardized questionnaires in CLBP. Although pain intensity measured by the NPRS did not differ significantly between sexes, women presented higher MPQ-derived scores and different qualitative pain descriptors. These findings suggest that qualitative pain expression may differ between sexes and should be interpreted within a broader biopsychosocial context.
