Applying the fear-avoidance model to exercise rehabilitation after coronary artery bypass grafting a nurse-led intervention study.
Trial report in Journal of cardiothoracic surgery, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
objectiveTo examine whether a nurse-led intervention grounded in the Fear-Avoidance Model (FAM) reduces postoperative kinesiophobia indirectly by improving patients' perceived physical capability.
methodWe conducted a single-center, parallel-group randomized controlled trial. A total of 122 patients who underwent coronary artery bypass grafting (CABG) were randomized 1:1 to an intervention group or a usual-care control group (n = 61 each). The intervention included graded activity, functional feedback, goal setting, structured education, and post-discharge follow-up. Perceived physical capability and kinesiophobia were assessed 30 days after discharge. Mediation analysis was used to test whether perceived physical capability mediated the effect of the intervention on kinesiophobia.
resultsThe intervention was associated with higher perceived physical capability (a = 2.43, p = 0.031). Perceived physical capability was inversely associated with kinesiophobia (b = - 0.775, p < 0.001). The indirect effect of the intervention on kinesiophobia through perceived physical capability was significant (ab = - 1.879; bootstrapped 95% CI [- 3.702, - 0.288]). In contrast, the total effect (c = - 1.557, p = 0.433) and the direct effect (c'=0.322, p = 0.860) were not statistically significant.
conclusionsThese findings suggest a rehabilitation-relevant pathway in which strengthening perceived capability may help reduce avoidance-oriented responses after CABG. A nurse-led approach that combines graded mobilization, performance feedback, and goal-based progression may support engagement in early recovery activities and may offer a practical framework for transitional rehabilitation support.
