The use of an alternating magnetic field in the resorption of postoperative joint effusion following anterior cruciate ligament reconstruction: A randomized double-blind controlled trial.
Trial report in Medicine, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
contextThere are no scientific reports unambiguously describing the efficacy of alternating magnetic field therapy in patients after anterior cruciate ligament (ACL) reconstruction in the early postoperative period.
objectiveThis study aims to evaluate the efficacy of using an alternating magnetic field in the resorption of postoperative joint effusion in patients after ACL reconstruction. STUDY
designA randomized, double-blind placebo-controlled study.
settingInpatients.
participantsForty patients were enrolled in the trial. However, the final study group consisted of 38 patients (28 men and 10 women) after ACL reconstruction who were randomly divided into an experimental group (19 patients) and a control group (19 patients).
interventionEach group received magnetic field therapy in the postoperative period, but only 1 apparatus emitted a magnetic field (the experimental group). Patients used the apparatus every day for 30 minutes for the next 11 days. The parameters in both devices were the same-3 mT and 10 Hz.
main outcome measuresThe measurement of the knee circumference and range of motion were made. The knee circumference measurement was performed before magnetic field therapy began and for 11 days after magnetic field treatment. The active knee range of motion was evaluated before and after magnetic field therapy was completed.
resultsThere were no statistically significant differences between the groups in the reduction of post-operative joint effusion or knee joint function.
conclusionIn patients after ACL reconstruction, in whom an alternating magnetic field was used to treat postoperative joint effusion, there were no beneficial effects on the analyzed variables compared to the control group.
