Figure 40-3 Survival function of four treatment groups stratified by age at current episode. Kaplan-Meier tests of survival function were significant for subjects ages 60-69 years (log rank = 25.9; df = 3; P = 0.001) and subjects 70 years or older (log rank = 9.05; df = 3; P = 0.03). Pairwise contrasts within each age stratum were not performed due to small sample sizes. IPT = interpersonal psychotherapy. Source.
