Joint Association of Occupational and Leisure-Time Physical Activity With Low Back Pain in Korean Adults.
Article in Musculoskeletal care, 2025. 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
objectiveThis study aimed to examine the effect of the interaction between gender-specific occupational physical activity (OPA) and leisure-time physical activity (LTPA) on low back pain (LBP) risk.
methodsData were obtained from a large-scale cohort survey of Koreans, comprising a total of 2750 participants recruited during 2011-2012. OPA and LTPA were assessed using validated questionnaires and classified into two groups: "< 150 min/wk" and "≥ 150 min/wk." LBP was defined based on the Oswestry Disability Index (ODI) and visual analogue scale (VAS) criteria. Multiple logistic regression analyses were performed to calculate odds ratios (OR) with 95% confidence intervals (CI), and multiple linear regression analyses were used to estimate β coefficients with 95% CI to assess the associations between OPA, LTPA, and LBP.
resultsThe results showed that increased OPA was significantly associated with higher ODI scores (β = 0.02, p = 0.021), whereas increased LTPA was significantly associated with reductions in both ODI (β = -0.07, p = 0.012) and VAS scores (β = -0.01, p = 0.013). Furthermore, engaging in OPA for ≥ 150 min/week was associated with an elevated LBP risk (OR = 1.38, 95% CI = 1.12-1.69), with significant gender differences observed. In contrast, for participants with < 150 min/wk of leisure-related physical activity, LBP risk increased (OR = 1.22, 95% CI = 1.01-1.76), whereas for those with ≥ 150 min/wk, LBP risk decreased (OR = 0.84, 95% CI = 0.66-0.95), a significant effect observed only in females.
conclusionThese findings suggest that ensuring adequate rest during OPA and promoting leisure-related physical activity may be critical strategies for reducing chronic LBP.
