*, **, ***—statistically significant results. a—continuous variable; b—categorical variable. Complete log—refers to analysis with the complete data set and the outcome variable (diagnostic delay) log transformed in the simple linear regression model. Filtered log—refers to analysis with 2 extreme diagnostic delay values removed and the outcome variable (diagnostic delay) log transformed in the simple linear regression model.
