↵† p = 0.001 for comparison with all admitted patients but no significance for comparison with the age-matched and sex-matched group of patients after Bonferroni correction.
↵‡ p = 0.004 for comparison with all admitted patients after Bonferroni correction (age and sex in both groups were similar, therefore there was no matched control group of patients).
↵§ p = 0.002 for comparison with all admitted patients but no significance for comparison with the age-matched and sex-matched group of patients after Bonferroni correction.
