The table illustrates the outcomes computed for two fictional patients with the same index date, one of whom was censored (because they died) during the follow-up period. Outcomes (number of visits, continuity of care) are counted over the full follow-up period for both patients, but the effective follow up is shorter for patient 2 because she is only observed for 2 years after the index date.
