Looking for a definition of aortic dilatation in overweight and obese individuals: body surface area-indexed values versus height-indexed diameters.

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
introductionPatient's body size is a significant determinant of aortic dimensions. Overweight and obesity underestimate aortic dilatation when indexing diameters by body surface area (BSA). We compared the indexation of aortic dimensions by height and BSA in subjects with and without overweight to determine the upper normal limit (UNL).
methodsThe MATEAR study was a prospective, observational, and multicenter study (53 echocardiography laboratories in Argentina). We included 879 healthy adult individuals (mean age: 39.7 ± 11.4 years, 399 men) without hypertension, bicuspid aortic valve, aortic aneurysm, or genetic aortopathies. Echocardiograms were acquired and proximal aorta measured at the sinus of Valsalva (SV), sinotubular junction (STJ), and ascending aorta (AA) levels (EACVI/ASE guidelines). We compared absolute and indexed aortic diameters by height and BSA between groups (men with body mass index [BMI] < 25 and BMI ≥ 25, women with BMI < 25 and BMI ≥ 25).
resultsIndexing of aortic diameters by BSA showed significantly lower values in overweight and obese subjects compared to normal weight in their respective gender (for women: SV 1.75 cm/m
conclusionWhile indexing aortic diameters by BSA in obese and overweight subjects underestimate aortic dilation, the use of aortic height index (AHI) yields a similar UNL for individuals with normal weight, overweight, and obesity. Therefore, AHI could be used regardless of their weight.
