Quality of life correlates with muscle strength in patients with dermato- or polymyositis.
Article in Clinical rheumatology, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 14 papers.
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
The aim of this study was to compare health-related quality of life (HQoL) in adults with dermatomyositis (DM) or polymyositis (PM) with a healthy control group and to assess whether muscle strength was associated with HQoL in patients with DM or PM. A cross-sectional study was performed and included 75 patients with DM or PM and 48 healthy controls. HQoL was assessed by the Short Form 36 questionnaire (SF-36). Muscle strength of the patients was assessed using the Manual Muscle Test-8 (MMT8). Covariables and possible confounding factors were collected by validated tools. Associations were determined in multiple linear regression models. The patients had significantly lower HQoL than the control group in both the physical component summary score (PCS) and the mental component summary score (MCS). Thus, the PCS-difference between groups was 32% (p < 0.001), whereas the MCS-difference was 14% (p < 0.001). Muscle strength was associated with one domain in the patients; Physical Function (β = 1.2; 95% confidence interval 0.37 to 2.1). No statistically significant associations were found between muscle strength and HQoL in the remaining domains. Patients with DM or PM have reduced HQoL compared to healthy controls. Notably, muscle strength was associated with scores of the domain reflecting perceived physical function in patients. These findings corroborate the validity of including selected patient reported outcomes in the evaluation and monitoring of patients with DM or PM.
