Table 2 Allelic status distribution in relation to distant relapse

From: Allelic imbalances of chromosomes 8p and 18q and their roles in distant relapse of early stage, node-negative breast cancer

Allelic type Number of patients No distant relapse (n) Distant relapse (n) OR p-value 95% CI
8pAI 47 28 19 Referent 0.18a (0.35, 2.83)
8pR 12 10 2 0.29   
18qAI 40 28 12 Referent 0.19 (0.59, 7.54)
18qR 19 10 9 2.1   
8pR/18qAI 11 10 1 Referent   
8pAI/18qR 19 10 9 9.0 0.049a (1.17, 69.47)
8pAI/18qAI 24 15 9 6.0 0.12a (0.76, 47.22)
  1. aP-values based on chi-square test and Fisher's exact test. Approximate 95% confidence intervals (CIs) was calculated for all Odds-ratios. AI, allelic imbalance; R, retention (no allelic imbalance); OR, odds ratio.
