Table 3 Power analysis of SNP markers

From: Association of common polymorphisms in known susceptibility genes with rheumatoid arthritis in a Slovak population using osteoarthritis patients as controls

SNP Published ORa Published MAF in controls Ref Current study's MAF in controls Powerb
rs2476601 1.98 0.10 [4] 0.108 94.5%
rs7574865 1.27 0.22 [5] 0.202 35.9%

  1. OR = odds ratio; MAF = minor allele frequency; Ref = reference; SNP = single nucleotide polymorphism.
  2. a combination of initial finding and replication (when available) in the cited study; effects from minor allele.
  3. b Power was calculated for published OR and MAF in controls from the present study (Table 4) with 520 cases and 303 controls assuming a one-tailed P = 0.05.
