Bariatric Surgery Improves Heart Geometry and Plasticity.
Article in Obesity surgery, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers, 1 of them a synthesis that pooled 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.
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
backgroundObesity is commonly associated with increased sympathetic tone, changes in heart geometry, and mortality. The aforementioned translates into a higher and potentially modifiable mortality risk for this specific population.
objectivesThe aim of the study was to analyze the extent of changes in the heart ventricular structure following rapid weight loss after bariatric surgery.
settingAcademic, university-affiliated hospital.
methodsWe retrospectively reviewed all the patients that underwent bariatric surgery at our institution between 2010 and 2015. Data analyzed included demographics, BMI, and associated medical problems. Preoperative and postoperative echography readings were compared looking at the heart geometry, cardiac volumes, and wall thickness.
resultsFifty-one patients who had bariatric surgery and had echocardiography before and after the surgery were identified. There were 33 females (64.7%). The mean age was 63.4 ± 12.0 years with an average BMI of 40.3 ± 6.3. The mean follow-up was 1.2 years after the procedure. At 1 year follow-up 25 patients (49%, p = 0.01) showed normal left ventricular geometry. The left ventricular mass (229 ± 82.1 vs 193.2 ± 42.5, p<0.01) and the left ventricular end diastolic volume (129.4 ± 53 vs 96.4 ± 36.5, p = 0.01) showed a significant modification following the procedure. There was a significant improvement in the interventricular septal thickness (p = 0.01) and relative wall thickness (p < 0.01) following surgery.
conclusionThe patients with obesity present a significant cardiac remodeling from concentric remodeling to normal geometry after bariatric surgery. The decrease in BMI has a direct effect on improvement of the left ventricular structure. Further studies must be carried out to define the damage of obesity to diastolic function.
