Relative-risk is the ratio of the percent of respondents in the high-risk cluster that experienced the adverse outcome compared to the percent in the other clusters or in the low -risk cluster.
Others = Respondents in either the intermediate-risk or low -risk clusters.
Positive Predictive Value is the percent of respondents in the high-risk cluster that experienced the adverse outcome; Sensitivity is the percent of observed adverse outcomes that occurred in the high-risk cluster.
These are dichotomous variables that differentiate respondents who had one or more of the following four adverse outcomes: in the top 5 percentile (or 10 percentile) of years with episodes, in the top 5 percentile (or 10 percentile) of years w ith episodes lasting most of the year, hospitalized, or disabled.
These are dichotomous variables that differentiate respondents who had two or more of the four adverse outcomes.
