Of the 1,991 participants who died by the end of the study, 1,410 had been interviewed for 3\u00a0years before death, including an interview 6\u00a0months before dying. We analyzed self\u2010reported mobility collected prospectively at 6\u2010month intervals during the last 3\u00a0years of life. We derived trajectories in two ways: by averaging decline within decedent groups prespecified according to clinical conditions and by estimating trajectory models using maximum\u2010likelihood semiparametric modeling.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Ninety\u2010eight percent of decedents were classified according to 4 prespecified clinical conditions (sudden death, terminal, organ failure, frailty), which produced groups with different characteristics.

Disability trajectory and clinical condition grouping confirmed previous research but were only marginally related.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Derived disability trajectories and grouping according to clinical condition provide useful information about different facets of the end\u2010of\u2010life experience.
