Clinical evaluation of usefulness and effectiveness of sitting-type continuous passive motion machines in patients with total knee arthroplasty: a dual-center randomized controlled trial.
Trial report in BMC musculoskeletal disorders, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
backgroundTotal knee arthroplasty (TKA) is a treatment option for osteoarthritis of the knee. After undergoing TKA, patients can be treated with continuous passive motion (CPM); however, inconsistent results have been reported on the effectiveness of CPM as part of a rehabilitation strategy. This discrepancy may be due to the difference between the set-arc of CPM and real arcs of knee motion. In this randomized controlled trial, we compared the efficacy of the sitting-type CPM, which can apply a more fitted arc of motion, to that of the conventional CPM.
methodsWe performed a prospective, multicenter, single-blind, three-arm, randomized controlled trial. Patients who underwent unilateral TKA were recruited and randomly allocated to three groups (151 participants; Group 1, conventional type; Group 2, mixed; and Group 3, sitting type). All participants underwent 10 days of CPM management. Passive and active ranges of motion (ROMs), pain, lower-extremity edema, patient-reported outcomes, and functional assessments were evaluated at four time points.
resultsPassive and active ROMs and pain significantly improved during and after the intervention in all groups; however, no significant differences were noted between the groups. Compared with the conventional type, the sitting-type CPM devices were rated higher in participant's satisfaction questionnaires.
conclusionThe sitting-type CPM had equivalent efficacy to that of the conventional-type CPM but provided higher satisfaction to patients after TKA. Therefore, the sitting-type CPM may be a useful tool in post-TKA rehabilitation. CLINICAL
