NOTE: χ2 test was used to examine associations between lymphocytes (0, 1+, 2+) and CNAs. Fisher's exact test was used when 25% of the cells had less than 5 observations. Effective sample size was 153. Categories were combined to identify associations driven by cases with either complete absence or abundance of lymphocytes.
