Impact of treatment strategy and physical performance on future knee-related self-efficacy in individuals with ACL injury.
Trial report in BMC musculoskeletal disorders, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 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
backgroundIn people with anterior cruciate ligament (ACL) injury, high self-efficacy facilitates recovery, indicated by improved muscle function, reduced knee symptoms and increased physical activity. Impact of treatment on future self-efficacy is however not well investigated. The aims of the study were to 1) investigate knee-related self-efficacy 6 years after acute ACL injury in patients treated with exercise therapy alone or in combination with either early or the option of delayed ACL reconstruction (ACLR), and 2) to investigate associations between single-leg physical performance at various time points after ACL injury and knee self-efficacy at 6 years after injury.
methodsParticipants (n = 121) originated from the KANON-study (ISRCTN84752559), a treatment RCT including active adults with acute ACL injury treated with structured exercise therapy combined with early or the option of delayed ACLR. In this ancillary study, participants with knee self-efficacy data at 6 years (n = 89) were analyzed as treated; exercise therapy alone (n = 20), exercise therapy plus early ACLR (n = 46), and exercise therapy plus delayed ACLR (n = 23). The participants performed physical performance tests (hop, strength and balance) at the end the of exercise therapy (mean 10 (SD 6) months), and at 5 years, and rated their knee self-efficacy using Knee Self-Efficacy Scale (K-SES) questionnaire (0 to 10, worst to best) at 6 years.
resultsMedian K-SES score for the total group (n = 89) was 7.8 (IQR 5.9-9.0). There were no differences between treatment groups in K-SES scores at 6 years nor in physical performance at any time point (p ≥ 0.097). Worse knee flexion strength LSI (r
conclusionKnee-related self-efficacy at 6 years after ACL injury did not differ between those treated with ACLR, performed early or as a delayed procedure, or exercise therapy alone. Good physical performance at the end of the exercise therapy, and at 5 years, appears to have a positive, yet small, impact on future knee-related self-efficacy.
