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

<p>Introduction: Excessive visceral fat area is a risk factor for postoperative complications in gastric cancer patients undergoing minimally invasive gastrectomy. This prospective pilot study aimed to evaluate the safety, compliance, and efficacy of prehabilitation in obese patients with gastric cancer who were scheduled to undergo curative gastrectomy.

methodsPatients with a preoperative visceral fat area ≥100 cm2 who were scheduled to undergo curative minimally invasive gastrectomy for stage I-III gastric cancer were included. The patients were instructed to walk 10,000 steps per day and consume a low-carbohydrate, high-protein diet without energy restrictions for 1 month before surgery. The primary outcome was the visceral fat area reduction rate, and clinical significance was set at a 10% reduction.

resultsEighteen patients were enrolled in the study, and no adverse events were observed. The mean number of steps per day was 10,572. The mean exercise time greater than or equal to moderate intensity was 42.3 min per day, and 88% of the patients completed the 1-month intervention. Although the skeletal muscle mass was preserved, the visceral fat area reduced by 17% (95% confidence interval: 11%-24%, p = 0.039).

conclusionPrehabilitation can safely reduce visceral fat area before performing minimally invasive gastrectomy in patients with gastric cancer who are obese. </p>.
