  1. Multivariate forward-step model: adjusted for age, sex, BMI, potassium, Calcium, and phosphate levels, diabetes, hypertension, hyperlipidemia, smoking. BMI: body mass index, CIdiff: coefficient variance of cardiac index (between 2nd and 1st hr of dialysis), CV: cardiovascular, DM: diabetes mellitus, HTN: hypertension, SVdiff: coefficient variance of stroke volume (between 2nd and 1st hr of dialysis).
