Evaluating the comparative efficacy of leg cycle ergometry exercise versus conventional physiotherapy on scar healing, muscle strength, functional capacity, and quality of life in coronary artery bypass graft subjects with saphenous vein graft in phase 1: a protocol for randomised controlled trial.
Article in Trials, 2025. 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
backgroundCoronary artery bypass grafting (CABG) is a common surgical treatment for coronary artery disease. The saphenous vein's advantageous anatomical features make it a popular choice for graft vessels. However, saphenous vein harvesting often results in lower limb complications such as edema, poor scar healing, pain, and reduced functional mobility. These issues can delay recovery and diminish quality of life. Early rehabilitation using leg cycle ergometry may improve outcomes, but comparative evidence with conventional physiotherapy in Phase I post-CABG care is limited.
aimTo determine the relative benefits of leg cycle ergometry training for CABG patients with saphenous vein graft in phase 1 in terms of scar healing, muscle strength, functional ability, and quality of life.
objectivesTo evaluate the comparative efficacy of leg cycle ergometry exercise versus conventional physiotherapy on scar healing, muscle strength, functional capacity, and quality of life in CABG subjects with saphenous vein grafts during Phase I rehabilitation.
methodsA randomized controlled trial will be conducted at Shalini Tai Meghe Super Speciality Centre with 70 CABG patients aged 45-65 years. Participants will be randomly allocated to Group A (conventional physiotherapy) and Group B (leg cycle ergometry with physiotherapy) for a 10-day intervention. Outcome measures include the Vancouver Scar Scale, Manual Muscle Testing, 6-Minute Walk Test, and Patient Health Questionnaire-9 (PHQ-9). Data will be analysed using the Mann-Whitney U test and the Wilcoxon signed-rank test; p<0.05 was deemed statistically significant.
resultsAs this is a study protocol, no results are available yet. It is hypothesized that leg cycle ergometry, when added to conventional physiotherapy, will lead to greater improvements in scar healing, lower limb strength, functional capacity, and short-term quality of life during Phase I cardiac rehabilitation following CABG surgery.
