^aColumn percentages

^bRow percentages

^cOnly one patient was under 15 years old, so < 15 group was merged into < 44 group

^dMigrant defined as patient coming from another county

^eStatistically significant

^fEven though some variables didn’t show statistical significance in univariate analysis, considering the important influence of patient’s background and diagnosis in the treatment management, we included all the variables in the multivariable analysis
