Link Between Positive Clinician-Conveyed Expectations of Treatment Effect and Pain Reduction in Knee Osteoarthritis, Mediated by Patient Self-Efficacy.
Trial report in Arthritis care & research, 2016. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 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
objectiveA prior knee osteoarthritis (OA) trial found that provider-conveyed expectations for treatment success were associated with pain improvement. We hypothesized this relationship was mediated by patient self-efficacy, since expectations of improvement may enhance one's ability to control health behaviors, and therefore health. Our aim was to examine whether self-efficacy was a mediator of the relationship observed in this trial.
methodsA secondary analysis of a 3-arm (traditional acupuncture, sham acupuncture, and wait list) trial for knee OA was conducted. Those in the acupuncture groups were equally randomized to acupuncturists trained to communicate a high or neutral expectation of treatment success (e.g., using language conveying high or unclear likelihood that acupuncture would reduce knee pain). A modified Arthritis Self-Efficacy Questionnaire and the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) pain subscale were administered. Linear regression analyses were used to examine whether patient self-efficacy mediated the relationship between provider communication style and knee pain at 3 months.
resultsHigh-expectation provider communication was associated with patient self-efficacy, β coefficient of 0.14 (95% confidence interval [95% CI] 0.01, 0.28). Self-efficacy was associated with WOMAC pain, β coefficient of -9.29 (95% CI -11.11, -7.47), while controlling for the provider communication style. The indirect effect a × b of -1.36 for high versus neutral expectation (bootstrap 95% CI -2.80, -0.15; does not include 0), supports the conclusion that patient self-efficacy mediates the relationship between provider-communicated expectations of treatment effects and knee pain.
conclusionOur findings suggest that clinician-conveyed expectations can enhance the benefit of treatments targeting knee OA symptoms, mediated by improved patient self-efficacy.
