The effect of problem-based learning after coronary heart disease - a randomised study in primary health care (COR-PRIM).
Trial report in BMC cardiovascular disorders, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT01462799 (COR-PRIM), which is not on this map. Cited by 10 papers, 3 of them syntheses 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.

Abstract
backgroundCardiac rehabilitation is effective after coronary heart disease (CHD). However, risk factors remain, and patients report fear for recurrence during recovery. Problem-based learning is a pedagogical method, where patients work self-directed in small groups with problem solving of real-life situations to manage CHD risk factors and self-care. We aimed to demonstrate the better effectiveness of problem-based learning over home-sent patient information for evaluating long-term effects of patient empowerment and self-care in patients with CHD. Hypothesis tested: One year of problem-based learning improves patients' empowerment- and self-efficacy, to change self-care compared to 1 year of standardised home-sent patient information after CHD.
methodsPatients (N = 157) from rural and urban areas in Sweden between 2011 and 2015 (78% male; age. 68 ± 8.5 years) with CHD verified by percutaneous coronary intervention (PCI) (70.1%) or coronary artery by-pass surgery (CABG) and CABG+PCI or myocardial infarction (29.9%) were randomly assigned to problem-based learning (experimental group; n = 79) or home-sent patient information (controls; n = 78). The problem-based learning intervention consisted of patient education in primary care by nurses tutoring groups of 6-9 patients on 13 occasions over 1 year. Controls received home-sent patient information on 11 occasions during the study year.
resultsAt one-year follow-up, the primary outcome, patient empowerment, did not significantly differ between the experimental group and controls. We found no significant differences between the groups regarding the secondary outcomes e.g. self-efficacy, although we found significant differences for body mass index (BMI) [- 0.17 (SD 1.5) vs. 0.50 (SD 1.6), P = 0.033], body weight [- 0.83 (SD) 4.45 vs. 1.14 kg (SD 4.85), P = 0.026] and HDL cholesterol [0.1 (SD 0.7) vs. 0.0 mmol/L (SD 0.3), P = 0.038] favouring the experimental group compared to controls.
conclusionsThe problem-based learning- and the home-sent patient information interventions had similar results regarding patient empowerment, self-efficacy, and well-being. However, problem-based learning exhibited significant effects on weight loss, BMI, and HDL cholesterol levels, indicating that this intervention positively affected risk factors compared to the home-sent patient information.
