Note: ALCC = area-level concentration coefficient, COPD = chronic obstructive pulmonary disease, DRD = disparity rate difference, DRR = disparity rate ratio, NA = not applicable.*Steps 1 to 6: Sort values in descending order and by rank. Step 7: Sum ranks for each outcome from step 1 to 6 and sort in ascending order).†Special focus (low prevalence, high inequality).
