1 · What the graph read from 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.

2 · The registry

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

objectivesThe purpose of this study was to compare the effectiveness of moderate-intensity stationary cycling and walking exercise programmes in the early postoperative period after first-time coronary artery bypass graft surgery.

methodsIn this prospective trial, 64 patients (57 men, 7 women, mean age = 66 ± 9 years) performed twice daily, moderate-intensity exercise sessions, of 10-min duration, from postoperative day 3 until discharge from hospital. Patients were randomly assigned to stationary cycling or walking exercise intervention groups. Preoperative and discharge functional exercise capacity and health-related quality of life were assessed using 6-min walk and cycle assessments and the SF-36 version 2.0 questionnaire. Compliance with exercise was calculated as the proportion of scheduled exercise sessions completed.

resultsThere were no significant differences between intervention groups at hospital discharge for 6-min walk distance (cyclists: 402 ± 93 m vs walkers: 417 ± 86 m, P = 0.803), 6-min cycle work (cyclists: 15.0 ± 6.4 kJ vs walkers: 14.0 ± 6.3 kJ, P = 0.798) or health-related quality of life. There was no significant difference between intervention groups for postoperative length of hospital stay (P = 0.335). Compliance rates for intervention groups were cyclists: 185/246 (75%) scheduled exercise sessions completed vs walkers: 199/242 (82%) scheduled exercise sessions completed (P = 0.162).

conclusionsStationary cycling provides a well-tolerated and clinically effective alternative to walking in the early postoperative period after coronary artery bypass graft surgery. The optimal frequency, intensity and duration of exercise in the early postoperative period require further investigation.
