  1. The multiple linear regression equation is given by: LOS (days) =2.60 + 1.54*(obesity) + 0.99*(DM) + 0.49*(HTN) + 0.96*(CAD) + ISS*0.64, depending on obesity (o = normal weight, 1 = obesity), DM (0 = no DM, 1 = DM), HTN (0 = no HTN, 1 = HTN), CAD (0 = no CAD, 1 = CAD), and ISS (scores) of these patients
