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

backgroundChanges in myocardial fat in addition to changes in cardiac structure and function have not been accurately evaluated in obese patients following surgery. MATERIALS AND

methodsForty-four obese patients who underwent sleeve gastrectomy and completed preoperative and postoperative cardiac magnetic resonance imaging (CMR) before surgery and at 1, 3, and 6 months after surgery were enrolled, and their clinical and laboratory data were collected. The differences and correlations between clinical, laboratory, and CMR parameters between the preoperative and postoperative groups were analysed.

resultsThe left ventricular mass (LVM), left ventricle cardiac output (LVCO), pericardial adipose tissue volume (PATV), and myocardial proton density fat fraction (M-PDFF) decreased after surgery (all P < 0.05). The left ventricle global longitudinal strain increased at 6 months after surgery (P = 0.004). A decrease in BMI was positively correlated with the LVCO (r = 0.58, P < 0.001) at 3 months after surgery and was positively correlated with the LVM and PATV (r = 0.54, P < 0.05) at 6 months after surgery. Six months after surgery, the changes in PATV were positively correlated with the changes in triglycerides (r = 0.61, P < 0.01). There was a moderately positive correlation between the decrease in the LVM and PATV (r = 0.54 ~ 0.71, P < 0.02) after surgery.

conclusionAfter surgery, the cardiac structure and function of obese patients significantly improved, the PATV and M-PDFF decreased, and there was a correlation between the structure and function of the heart and several clinical and laboratory indicators.
