Reliability and construct validity of the modified Finnish version of the 9-item patient health questionnaire and its associations within the biopsychosocial framework among female health-care workers with sub-acute or recurrent low back pain.
Article in BMC musculoskeletal disorders, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT01465698 (Effectiveness and Financial Feasibility of Neuromuscular Exercise and Counselling Interventions on Pain, Movement Dysfunction, and Fear-avoidance Behaviour in Female Nurses With Non-specific Low Back Pain), which is not on this map.

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.

Abstract
backgroundHealth-care workers have an increased risk for chronic low back pain (LBP) leading to reduced workability. Depression, a highly prevalent, costly and disabling condition, is commonly seen in patients with sub-acute LBP. This study investigated the psychometric properties and construct-validity of a modified 9-item Patient Health Questionnaire (PHQ-9-mFIN) in female health-care workers with sub-acute LBP.
methodsReliability (internal consistency, test-retest repeatability) was assessed using standard methods. Construct validity of the PHQ-9-mFIN was assessed as level of depressive symptoms (PHQ-9-mFIN: 0-4 none, 5-9 mild, ≥10 at least moderate) against the RAND 36 Health Survey, a valid measure of health-related quality of life (HRQoL). Additionally, the strength of the association between the levels of PHQ-9-mFIN and selected biopsychosocial factors was determined.
resultsThe internal consistency of the PHQ-9-mFIN was high (Cronbach's α = 0.82) and the test-retest repeatability scores (n = 64) were moderate: Pearson's correlation was 0.73 and Intraclass Correlation Coefficient (ICC) 0.73 (95% CI: 0.58 to 0.82). Construct validity (Spearman correlation) against the Physical and Mental component items and their summary scales of the RAND 36 were much higher for the Mental (range, - 0.40 to - 0.67 and - 0.64) than for the Physical (range, - 0.08 to - 0.43 and - 0.22). There was a clear stepwise association (p < 0.001) between the levels of depressive symptoms and General health (physical component, range, 59.1 to 78.8). The associations with all items of the Mental components were strong and graded (p < 0.001). All participants had low scores for Bodily pain, regardless of the level of depressive symptoms. There was a strong association (p ≤ 0.003) between the levels of PHQ-9-mFIN and multisite pain, lumbar exertion and recovery after workdays, neuromuscular fitness in modified push-ups, workability, and fear of pain related to work.
conclusionsThe PHQ-9-mFIN showed adequate reliability and excellent construct validity among female health-care workers with recurrent LBP and physically strenuous work.
