The null hypothesis is that predicted biological age is unrelated to 10-year survival. Tests of Biological Age. Four groups of researchers have compared Borkan (1978) compared the mean biological age profiles for several health-based subgroups of participants. Data collected among the Mennonites included variables used in other studies of biological age, body morphology, and blood In that research Uttley regressed individual variables against chronological age. functional age residuals are listed by variable set, town, sex, and survival that predicted functional age is unrelated to 10-year survival was tested suggested that with variables correlated with chronological age the resulting predictive functions may actually be unrelated to survival. ./cache/work_xwfzwinware6nd4s6rxcukff2q.pdf ./txt/work_xwfzwinware6nd4s6rxcukff2q.txt
