  1. Results are compared with Finnish and Nigerian patients in different subgroups. P value gives the statistical significance of the relationship between apoptotic counts (AI) and characteristics of the patient groups (t test, X² test, ANOVA). *NA not available. AI apoptotic activity index: SD standard deviation.
