(a) Failure plots for probability of survival at 90 days between the BB/Bb and bb genotypes. No significant difference between the two subgroups was found (log rank, p = 0.173). (b) Failure plots for probability of survival at 90 days between the FF/Ff and ff genotypes. No significant difference between the two subgroups was found (log rank, p = 0.955). (c) Failure plots for probability of survival at 90 days among patients with the FF/Ff genotype with high 1,25-dihydroxyvitamin D levels, the FF/Ff genotype with low 1,25-dihydroxyvitamin D levels, the ff genotype with high 1,25-dihydroxyvitamin D levels, and the ff genotype with low 1,25-dihydroxyvitamin D levels. No significant difference among the four subgroups was found (log rank, p = 0.218).
