Predicting low back pain-related absenteeism in the Spanish general working population.
Observational study in Occupational and environmental medicine, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT00667316 (Study to Identify the Influence of Different Factors on Workers' Disability Due to Low Back Pain), which is not on this 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.

Abstract
objectivesTo identify factors associated with an increased risk of low back pain (LBP)-related sick leave and to develop prognostic models for both the likelihood and duration of such leave.
methodsA total of 7262 actively working adults were recruited consecutively during their annual check-ups. Seventy-seven variables were assessed, including sociodemographic, clinical, work-related, LBP-related and psychosocial factors. Outcomes included the occurrence of LBP-related sick leave and the number of days on leave over an 18-month follow-up period. Multivariable prognostic models were developed
resultsDuring the follow-up, 535 participants (7.4%, 95% CI 6.8 to 8.0) took LBP-related sick leave, of whom 162 were off work for ≥30 days. Predictors of taking sick leave were older age, not being self-employed, a usual LBP episode duration >14 days, higher job insecurity, greater self-expectations of taking sick leave and stronger perceived economic consequences of being on leave. Predictors of longer sick leave (≥ 30 days) were not being self-employed and experiencing LBP while in bed. The models demonstrated good calibration but poor discrimination (C-statistics: 0.607 and 0.604).
conclusionPredicting LBP-related sick leave and its duration among the general Spanish workforce remains challenging. Psychosocial and economic variables outweigh clinical or biological predictors. Self-employment is the only factor associated with a lower risk of both sick leave and being off work for ≥30 days. TRIAL REGISTRATION NUMBER: NCT00667316.
