*Per = the percentile-transformed predicted score on the persistence outcome variable; Chr = the percentile-transformed predicted score on the chronicity outcome; Hos = the percentile-transformed cumulative predicted probability of hospitalization; Dis = the percentile-transformed predicted probability of disability. ¹k-means cluster analysis of percentile-transformed predicted scores on the four outcomes for all respondents based on the Lasso GLM
