Table 2 Correlation of TNF levels with genotypes of the -1031 and -863 SNPs in controls and patients. Comparison of means was carried out by Kruskal-Wallis test.

From: Polymorphisms of TNF-enhancer and gene for FcγRIIa correlate with the severity of falciparum malaria in the ethnically diverse Indian population

  1. 'n' indicates number of individuals in each category.
  2. a,b TNF levels in TT vs. CC in controls and patients: P < 0.01 (Mann-Whitney test)
  3. c,d TNF levels in CC vs. AA in controls and patients: P < 0.02 (Mann-Whitney test)
