Data are represented as median ± interquartile range. aAdipocyte size shows the mean of cell diameter in µm. bSVF was estimated by summing events positive for CD31, CD34 or CD45. cPercentage of the CD11c+phenotype within macrophages. dPercentage of T-cytotoxic phenotype within T-lymphocytes. The remaining variables show 103 cells/g of adipose tissue. ***P < 0.001, **P < 0.01, *P < 0.05 when comparing both types of adipose tissue in morbidly obese patients. ###P < 0.001, ##P < 0.01, #P < 0.05 when comparing both types of adipose tissue in ex-morbidly obese patients.
