0, 0, 0, 0, 99, 99]. The frequency of right-censored probands across the age intervals was: 0 for w1–w4, 1 for w5, 42 for w6, and 152 for w7. This illustrates a relative sparseness of data at the last age interval (50+ years) due to the fact that the average proband age during the most recent assessment (T25) was 47 years. It should be noted that since no probands met criteria for AUD at the baseline interview (per screening requirements), no left-censoring was needed for the current analyses.
