miRNA-195 expression levels in plasma samples of healthy controls and different tumor node metastasis (TNM) stages (I, II, and III) of non-small cell lung cancer (NSCLC) patients. Mann-Whitney U test was used to determine statistical significance. The upper and lower limits of the boxes and the lines inside the boxes indicate the 75th and 25th percentiles and the median, respectively. The whisker caps indicate the 90th and 10th percentiles. *P < 0.01
