Low visceral adipose tissue regulatory T cells are associated with higher comorbidity severity in patients undergoing bariatric surgery.

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
backgroundAdipose tissue (AT) inflammation is linked to the development of type 2 diabetes (T2DM) and atherosclerosis in murine models of obesity. Reduced AT regulatory T cells (Tregs), which are anti-inflammatory immune cells, play an important part in this pathogenesis, and we have shown that AT-Tregs are inversely correlated to increasing body-mass-index. The purpose of this study was to evaluate the association between AT-Treg abundance and comorbidity status in patients undergoing bariatric surgery (BS).
methodsVisceral (intra-abdominal) AT was harvested at that time of primary BS (n = 80) and collagenase digested. AT-Treg abundance (CD4+/CD25+/FOXP3+) was characterized using flow cytometry from the AT stromal vascular fraction. The median AT-Treg abundance (3.03%) was utilized to define high (High-Tregs, n = 39) and low AT-Treg (low-Tregs, n = 38) abundance within this cohort. These two groups were compared in terms of baseline demographic data, preoperative obesity-related comorbidities, glycemic parameters, including insulin resistance (HOMA-IR).
resultsAge, excess body weight, and sex were not different between groups. Prevalence of hypertension, hyperlipidemia, or T2DM preoperatively were not different between groups. Compared to High-Tregs, patients with low-Tregs were more likely to have insulin-dependent type 2 diabetes (12.5% vs 2.9%, p = 0.04). Within patients with T2DM, low-Treg patients had higher plasma insulin levels compared to high-Tregs (31.8 (28.4-56.5) vs 15.5 (10.1-23.1), p = 0.04) and trended towards higher insulin resistance (HOMA-IR) (9.0 (5.3-18.3) vs 3.5 (2.2-7.7), p = 0.08). Within those diagnosed with hyperlipidemia, preoperative statin use was higher in Low-Treg patients compared to the control cohort (91% vs 50%, p = 0.056). Low-Treg patients with hypertension were more likely to need 2 + anti-hypertensive agents preoperatively compared to their counterparts (71% vs 44%, p = 0.058).
conclusionWithin bariatric candidates, lower visceral AT-Treg abundance was associated with increased baseline medication requirements for type 2 diabetes, hypertension, and hyperlipidemia. This suggests that reduced AT-Tregs may be associated with higher obesity-related comorbidity severity.
