We read with interest the article by Sujanyal et al. investigating the outcomes of LUCAS®-assisted versus manual cardiopulmonary resuscitation (CPR) in obese patients with in-hospital cardiac arrest (IHCA) across seven Mayo Clinic hospitals [1]. Their rigorous propensity-weighted analysis addresses a timely and relevant clinical question given the increasing prevalence of obesity among hospitalized patients. While the authors report no significant difference in 24-hour or 60-day mortality between manual and mechanical CPR, we believe several critical methodological and contextual aspects warrant further discussion.
