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

backgroundPhysical prehabilitation can enhance patient resilience to surgical stress, but its effects are unclear in vulnerable and frail patients. We aimed to determine the effect of a structured exercise prehabilitation programme on the quality of recovery after cardiac surgery in vulnerable and frail participants.

methodsThis single-blinded, parallel-arm, superiority, randomised controlled trial recruited patients with a Clinical Frailty Scale of 4-6 undergoing cardiac surgery. Patients were randomised to either physical prehabilitation (twice weekly) or standard care (control); both arms received standard perioperative care. The primary outcome was Quality of Recovery-15 (QoR-15) score on the third day after surgery. Secondary outcomes included major adverse cardiac and cerebrovascular events (MACCE), days alive and at home (DAH

resultsOf 164 randomised patients, 138 were included in the primary analysis (median age 64 [interquartile range 60-69] yr; 70% males). Compliance with the 5-week prehabilitation programme was high (82%), with no adverse exercise-induced events reported. There were no between-group differences in QoR-15 scores (median difference -3, 95% confidence interval [CI] -9 to 3), early and late MACCE, and DAH

conclusionsA 5-week programme of physical prehabilitation in predominately prefrail patients was safe, but it did not enhance quality of recovery scores after surgery. Prehabilitation resulted in a clinically meaningful decrease in disability scores at 90 days after surgery. CLINICAL
