  1. COVID-19 coronavirus 2019 disease, CI confidence interval, BMI body mass index.
  2. Mortality vs. recovery.
  3. After adjustment for sex, BMI, past history of diabetes mellitus, hypertension, ischemic heart disease, creatinine, phosphor, albumin.
  4. Odds ratio change in mortality per standard deviation increase in scale independent variable. Each odds ratio result is adjusted for each of the other independent variables in the table.
