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

introductionObesity and heart failure with left ventricular ejection disfunction (LVED) are intertwined and rising worldwide. Weight loss through bariatric surgery improves cardiac function. We aimed to assess the incidence of perioperative complications in patients with severe obesity and LVED who had bariatric surgery, and the long-term effectiveness of surgery.

methodsIn a single-center observational retrospective study, we compared patients with body mass index ≥35 kg/m

resultsOverall, 79 patients were included, 38 with LVED (LVEF, 35 ± 9%) and 41 controls (LVEF, 59 ± 5%). There were not differences in baseline characteristics. The overall incidence of postoperative complications was similar. Patients with LVED had higher rate of minor complications (Clavien-Dindo grades 1 and 2, p < 0.05), which did not affect hospital length of stay (4 ± 5 vs. 3 ± 1 days) (p). After one year, bariatric surgery was effective with overall total weight loss of 34 ± 20%. Patients with LVED showed a 6 ± 10% increase in LVEF, and improvement in functional capacity.

conclusionPatients with LVED have higher incidence of minor complications after bariatric surgery with no impact on length of hospitalization. Bariatric surgery is associated with a significant improvement in both LVEF and functional capacity.
