Note: Numbers in the table reflect treatment-control-group differences in nursing home use during the first year after entry to the study. First-year data were not reported by some projects. For these, first-year use was estimated from project data whenever possible. Percentage of users was estimated based on the assumption that the time between entry to the study and when a given subject enters a nursing home follows an exponential distribution. Such a representation is suggested by DeGroot (1975). Key to symbols: “a” to “r” superscripts refer to table notes located in Appendix B. “T-C” indicates the control-group average was subtracted from the treatment-group average. “∼” indicates the statistical significance of the treatment-control-group difference was not reported. “*” indicates the treatment-control-group difference was statistically significant at the 5 percent level. The results of statistical significance tests are from tests conducted by project evaluators (e.g., on an observed 6-month difference), not by the authors on an estimate of a 12-month difference. “#” indicates the statistical significance of the treatment-control-group difference was assessed using multivariate techniques to control or adjust for baseline characteristics. Adjusted estimates are presented whenever reported. “—” indicates data were not available.
