Re: Association between low functional health literacy and mortality in older adults: longitudinal cohort study

The title of the report looks strange "longitudinal cohort study". If there will be "prospective cohort study" the reader may understand that authors underscore the prospective character of the study. If there will be "retrospective cohort study" the reader may understand that he is informed about the retrospective data collection for the study.

The "longitudinal cohort study" formula is senseless, because both adjectives are almost perfect synonims.
