Effect of functional relaxation on the quality of life in patients with periprosthetic joint infection: Protocol for a randomised controlled trial.
Article in BMJ open, 2022. 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
introductionPeriprosthetic joint infection (PJI) is a devastating complication in orthopaedic and trauma surgery, which puts a high burden on the patients involving recurrent hospitalisation, prolonged courses of antibiotic medication, severe pain and long periods of immobility as well as high levels of psychological distress. Thus, this multicentre study aims at implementing body-oriented psychotherapy in clinical practice and evaluating its therapeutic effect on the quality of life. METHODS AND ANALYSIS: A prospective, parallel two-armed randomised controlled trial with approximately n=270 patients with verified PJI treated surgically with a one-staged exchange, or a two-staged exchange will be conducted. Functional relaxation (FR) therapy will be implemented as a group therapy. FR originally belongs to the psychodynamically based body-oriented psychotherapy. Intervention techniques consist of minute movements of small joints, which are performed during relaxed expiration accompanied by an exploration of differences of body feelings. A group will include 3-8 patients, led by a specialist physiotherapist certified in FR once a week. The participants are consecutively admitted to the class and participate in 12 sessions. The control group will consist of patients receiving an unspecific 'placebo relaxation' intervention for the same duration. The primary efficacy endpoint is the mental component summary and physical component summary of quality of life assessed by the 36-Item Short Form Health Survey (SF-36) after 6 months. Secondary outcomes include SF-36 scores after 12 months, consumption of pain medication, mobility measured by the Parker mobility score and the physical activity measured by daily steps with an accelerometer (actibelt). ETHICS AND DISSEMINATION: Approval from the Ethical Committee of the University Hospital Regensburg was received (file number: 21-2226-101). Written, informed consent to participate will be obtained from all participants. Results will be made available in the form of peer-reviewed publications and presentation in congresses.
