Whole body DXA was performed using a Hologic Delphi A scanner equipped with software version 12.5 (Hologic, Bedford, MA, USA). Then, the obtained DXA images were reanalyzed using Apex version 5.6 (Hologic, Bedford, MA, USA), with the National Health and Nutrition Examination Survey (NHANES) option enabled. Subject position and ROI placement were performed in accordance with the manufacturer’s instructions [25 (link)]. Estimates, including total body fat mass, trunk fat mass, android fat mass, total percentage fat (PBF), trunk percentage fat (PBF_TR) and VAT, were generated and compared to VAT obtained by using MRI (VATMRI).

Participants completed one whole‐body dual energy X‐ray absorptiometry (DXA) scan on a Hologic Discovery/A or Horizon/A system (Hologic Inc.). As described in detail previously,19 DXA scans were all centrally analyzed at UHCC by a trained technologist using Hologic APEX version 5.6 with the (NHANES) Body Composition Analysis calibration option disabled. DXA cross‐calibration phantoms were circulated between all sites and calibration equations derived to remove systematic bias in all bone and soft tissue results. Among other measures, total and percent body fat were derived.
About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
