Highly accurate colorectal cancer prediction model based on Raman spectroscopy using patient serum

Figure 4 Comparison of intensity. Outlier box plot depicting the intensity of the scattered light of the sera from the studied patients. The bottom and top parts of the box show the lower and upper quartiles, and the band across the box indicates the median. The lower and upper bars at the ends of the whiskers show the lowest data point within a range spanning 1.5 interquartile ranges of the lower quartile, and the highest data point within a range spanning 1.5 interquartile ranges of the upper quartile. The dots denote outliers that extend beyond the whiskers. The diagonal square indicates average values. However, with no significant deference, the mean scattered light intensity of A8 is higher in the cancer group (235.6) than in the adenoma (229.4), hyperplastic polyp (229.7), and other disease and/or no specific findings (231.0) groups. In addition, with no significant deference, the mean scattered light intensity of A10 is lower in the cancer group (263.4) than in the adenoma (272.4), hyperplastic polyp (272.1), and other disease and/or no specific findings (271.6) groups. With a slight difference, the mean scattered light intensity of A3 tended to be lower in the cancer group (251.3) than that in those with adenomas (255.2), hyperplastic polyps (254.9), and other disease and/or no specific findings (253.9).
