Expression of miR-125a-5p and miR-34a-5p in cohorts 3 and 4. RS was predicted in samples indicated with black asterisks. (A) RS is predicted by high expression of miR-125a-5p in 11 out of 36 samples from cohort 3. (B) Low expression of miR-125a-5p in control cohort 4. (C) RS is predicted by low expression of miR-34a-5p in 10 out of 36 samples from cohort 3. (D) High expression of miR-34a-5p in control cohort 4. False positives are indicated by red asterisks. Samples showing expression of miR-34a-5p very close to the established threshold are indicated with a red arrow.
