Immune Parameters in a Longitudinal Study of a Very Old Population of Swedish People: A Comparison Between Survivors and Nonsurvivors

Abstract

As a part of an ongoing longitudinal investigation, this study examined relationships between survival and selected immune system parameters in a sample (n = 102) of very old individuals (86-92 years at the time of initial immune system data collection). Analyses were performed comparing initial time-point measurements from those individuals who were alive (n = 75) and those who were deceased (n = 27) two years after initial data collection. Immune system measurements consisted of determination of peripheral blood lymphocytes and lymphocyte subsets, as well as T-cell responses to activation by Concanavalin A. Cluster analysis identified a subgroup associated with nonsurvival which indicated characteristics that included: poor T-cell proliferative responses, high CD8 percentages, and low CD4 and CD19 percentages. This multivariate analysis suggested that combinations of immune system parameters predict two-year survival otherwise not apparent when single immune system parameters were evaluated in the elderly.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
