a Cond 1 and Cond 2 indicate the conditions into the premises of the rules.
b The covering accounts for the fraction of patients that verify the rule and belong to the target outcome.
c The error accounts for the fraction of patients that satisfy the rule and do not belong to the target outcome.
d Fisher p-value quantifies the statistical significance of the rule on the basis of the number of patients correctly and incorrectly classified by a rule and the number of patients of the dataset belonging to each specific outcome.
