Table 1:
Unadjusted and survey-weighted population characteristics of individuals excluded from the analysis for a reason other than age. Note that adjusting for survey weights can result in non-integer estimates for categorical variables (i.e. 444.7 individuals with Diabetes included in the analysis). We rounded the survey weighted categorical variables to the nearest integer. P-values associated with continuous variables were calculated using t-tests, while chi-squared tests were used for categorical variables.
