Nomogram predicting the risk of malignant tumors in MN patients. The nomogram incorporates glomerular IgA, IgG1, IgG2, IgG3, IgG4, and PLA2R deposition as predictors. For each predictor, the corresponding point value is determined along the top scale, and the total points are calculated by summing the points for each predictor. The total points are then mapped to the predicted malignant tumor risk on the bottom scale
