NOTE: χ2 test was used to examine associations between lymphocytes (0, 1+, 2+) and mutations (0, 1). Fisher's exact test was used when 25% of the cells had less than 5 observations. Effective sample size was 99. Categories were combined to identify associations driven by cases with either complete absence or abundance of lymphocytes. Bolded P values are <0.05.
