RGS18 and cancer: The ROC curves for cancer diagnosis using log2(RPM+1) or log2(RPKM+1) showed that RGS18, SNORA12, and SNORD97 had higher area under the curve (AUC), sensitivity, and specificity than RGS18 alone or both SNORA12 and SNORD97 (0.992, 96.7%, and 100% for RGS18, SNORA12, and SNORD97; 0.964, 96.7%, and 91.7% for RGS18; and 0.883, 73.3%, and 100% for SNORA12 and SNORD97; Figure 5H).
