CHIEF INDICATORS · population overview
Cohort remaining/alive
Snapshot dates: 1/1/19 at time zero, then 31/12/19 through 31/12/24. Absence of a routine visit does not remove a person from the cohort.
Observed during interval
Baseline is shown without an artificial year label. Protocol year YYYY is the project-defined annual interval; a person may be unobserved in one period and observed again later.
Number of visits per year
Six follow-up panels (2019-2024). Class 0 means cohort member with no qualifying visit during that protocol year; it is not labelled as a missing clinical measurement.
