Table 2 Genotype and allele frequencies of IL1RA VNTR polymorphism in Thai malaria patients.

From: A functional polymorphism in the IL1B gene promoter, IL1B -31C>T, is not associated with cerebral malaria in Thailand

  1. Frequencies are in parentheses.
  2. a P-values were calculated by the Fisher's exact test based on 5 × 2 and 4 × 2 contingency tables for genotype and allele frequency, respectively.
  3. bIt should be noted here that allele with n repeats of VNTR is designated as "n" in this table.
