MYOF and neoplasm: ROC curve analysis evaluating the predict value of expression of MYOF and the other five genes showed that high expression of MYOF was more likely to be found in tumor than in normal tissues (cut-off, 4.838; AUC, 0.710; 95% CI, 0.614–0.806; Youden index, 0.562; sensitivity, 0.765; specificity, 0.562) (Figure 1F; Table 1).
