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

backgroundEsophagectomy confers high postoperative morbidity and mortality. To improve postoperative outcomes, this study investigated the effectiveness of a 2-week prehabilitation program on the preoperative cardiopulmonary function of patients undergoing surgery for esophageal cancer.

methodsIn this parallel-group, open-label, superiority randomized clinical trial, participants were randomly assigned (1:1) to the multimodal prehabilitation (m-prehab) group or the control group and received exercise instruction from a physical therapist. The m-prehab group received additional exercise instruction 1 week later and were administered additional oral nutritional supplements (430 kcal and 47 g protein 2 weeks before surgery). The primary outcome was change in the anaerobic threshold (AT) from baseline to immediately before surgery.

resultsAmong the participants (42 men and 8 women; m-prehab [n = 25], control [n = 24]; mean age, 65.3 years), those in the m-prehab group consumed significantly more protein than those in the control group (76.8 ± 16.6 vs 61.6 ± 18.0 g/day, p < 0.01). The m-prehab and control groups showed no significant intergroup difference in preoperative daily step counts (7590 and 7910, respectively) or change in AT. Quadriceps strength increased significantly more in the m-prehab group than in the control group (3.7 ± 13.5 vs - 5.3 ± 16.0; p = 0.04), and the skeletal muscle index showed a nonsignificant but increasing trend (4.0 ± 6.5 vs 1.1 ± 4.8; p = 0.09). Estimated protein intake was unassociated, whereas preoperative step count was significantly correlated positively with change in AT (r = 0.412; p = 0.02).

conclusionsThis prehabilitation program increased preoperative protein intake but did not contribute to an increase in physical activity, nor did it result in significant differences in preoperative changes in AT.
