Association between metabolic syndrome and risk of incident low back pain: A retrospective cohort study using real-world data from Japan.
Article in Preventive medicine reports, 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
Objectives: Obesity is a well-established risk factor for low back pain (LBP). Emerging evidence suggests that other metabolic abnormalities may also be associated with LBP; however, the association between metabolic syndrome (MetS) and LBP remains unclear. This study assessed the association of MetS with the risk of incident LBP using longitudinal real-world data from Japan. Methods: Health insurance claims and health checkup data from prefectural government employees across all Japanese prefectures except Tokyo (April 1, 2018-March 31, 2023) were linked. Incident LBP was identified from claims, and MetS status from checkups. Participants who underwent a health checkup between April 1, 2018 and March 31, 2019 with no LBP that year were followed from April 1, 2019 to March 31, 2023. Cox proportional hazards models estimated hazard ratios (HRs) and 95 % confidence intervals (CIs) to explore the association of MetS with LBP risk. Results: Among 111,095 participants (mean follow-up: 3.3 years, 362,911.7 person-years), 16,894 developed LBP (15.2 %). MetS was associated with a significantly higher LBP risk (HR = 1.24; 95 % CI, 1.19-1.30). In sex-stratified analyses, the HR was 1.23 (95 % CI, 1.17-1.29) for males and 1.34 (95 % CI, 1.17-1.54) for females. Participants with abdominal obesity with additional MetS components had a greater LBP risk than those with abdominal obesity alone. Conclusion: MetS may be a predictor of incident LBP, highlighting the potential value of MetS management in LBP prevention.
