Figure 2. Scatter plots of RLM of interest biomarkers and combining predicts of C1, C2, and C3 in the training set.

For each scatter plot, the dotted line represents the best cutoff value; Mann-Whitney test was performed across groups: ns = p > 0.05, *= p ≤ 0.05, **= p ≤ 0.01, **** = p ≤ 0.0001; HV: healthy volunteer, IUC: infected urinary calculi, PC: prostate cancer; KC: kidney cancer, UCC: urothelial cell carcinoma.
