- Note: MH=CIfs-CIss.CIss and CIff are the CI’s in periods s and f respectively, and CIfs is the CI obtained when health outcomes in the final period are ranked by SES in the initial period. MR = CIff –CIfs.CIff and CIfs are the CI’s in periods f, and CIfs CI obtained when health outcomes in the final period are ranked by SES in the initial period. CI△s represents mean health change ranked by initial rank (the concentration coefficient of health changes ranked by initial period income)
