Girth, strength, and flexibility of the calf muscle in patients with knee osteoarthritis: A case-control study.
Article in Journal of Taibah University Medical Sciences, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers, 1 of them a synthesis that pooled it.
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
objectivesReduced strength and girth in thigh muscles such as the quadriceps and the hamstrings have been observed in patients with knee osteoarthritis (OA). However, studies on the characteristics of calf muscles in these patients are lacking. This study aimed to evaluate the girth, strength, and flexibility of the calf muscle of patients with knee OA.
methodsIn this case-control study, we recruited 15 patients with knee OA and 15 healthy control participants. The girth, strength, and flexibility of the calf muscle were evaluated in one session using a flexible non-elastic tape measure (centimetre), a handheld dynamometer (Newton), and a standard goniometer (degree) to measure ankle dorsiflexion.
resultsStrength of the calf muscle strength was significantly lower in the patients with knee OA comapred with the control group (-42.03; 95% CI: -73.9, -10.1;
conclusionIn our study, patients with knee OA demonstrated reduced calf muscle strength. We recommend that the management of patients with knee OA include strengthening the calf muscles.
