Paired samples total cholesterol levels. Total cholesterol levels in tumor tissue were measured using a cholesterol assay before and after 2 weeks of treatment with 80 mg atorvastatin daily. The tumor tissue total cholesterol content was higher in 11 of the 14 paired samples after 2 weeks of atorvastatin treatment lower than before treatment in the remaining three cases. No statistically significant differences in the levels of total cholesterol were observed [P = 0.11 (Wilcoxon signed-rank test)]
