• The risk of developing diabetes was estimated, using life-table methods, by years of follow-up and age, according to genetic factors (shared HLA-haplotypes, DR antigens, C4 allotypes) and islet cell antibody status [22].
• For the subsamples (levels and areas of oral cavity) studied, the numerical distribution of TNM categories, life tables and life table comparisons were computed [23].

Associations of Life Tables with chemical compounds

• A life-table method of analysis showed that the ulcer relapse rate was consistently and significantly lower on ranitidine that on cimetidine (8% v 21%, p = 0.0018 at 4 months; 14% v 34%, p less than 0.0001 at 8 months; and 23% v 37%, p = 0.004 at 12 months) [24].
• These differences were statistically significant in favor of famotidine at weeks 6 (p less than or equal to 0.01) and 8 (p less than or equal to 0.05), as well as in a life-table analysis (p less than or equal to 0.05) [25].
• Life-table analysis showed ongoing remission after 6 and 12 mo for Pentasa to be 63% (26 of 41) and 54% (22 of 41) and for Salazopyrin 72% (22 of 31) and 46% (14 of 31) [26].
