Influence of severe knee pain, meniscus surgery and knee arthroplasty on physical ability: an observational study of 114 949 adults in the CONSTANCES cohort.
Observational study in BMJ open, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
backgroundThe knee is one of the major sites of musculoskeletal pain, yet few large-scale studies have evaluated the impact of knee disorders on physical limitations. Our objective was to describe this impact in a large-scale population study.
methodsWe included subjects of working age from the CONSTANCES cohort, from its inception. Four groups were distinguished according to their medical history: whether they had knee arthroplasty (KA), meniscus surgery, severe knee pain, or none of these. Outcomes assessed for physical limitations were self-reported limitations in the last 6 months due to health problems, limitation on carrying 5 kg on 10 m and a 3-metre length rapid gait speed test (for participants aged >45). Associations between knee groups and patients' characteristics and physical limitations were analysed using logistic regression. Robust associations were deemed relevant if their ORs were higher than 2 and their p value lower than 0.0001.
resultsOf the 114 949 individuals, 99 052 (86.2%) were in the 'no pain and no surgery' group, 14 740 (12.8%) were in the severe knee pain group, 1019 (0.89%) had meniscus surgery and 138 (0.12%) had KA. Severe knee pain and KA groups showed a similar profile (they were less at work, reported more deterioration in their health and had more limitations).
conclusionAlmost 14% of the sample had knee disorders. Subjects reporting severe knee pain or who had KA reported more important physical limitations then subjects who reported neither severe knee pain nor knee surgery.
