Recurrence-free survival (RFS) analyses of biological characteristics and p-value heatmap of meningioma comparing recurrence. (A) RFS analysis comparing older (age ≥ 56 years) with younger (age < 56 years) patients. (B) RFS analysis comparing WHO grade I lesions with grades II and III ones. (C) RFS analysis comparing Ki67 > 5% lesions with Ki67 ≤ 5% ones. (D) RFS analysis comparing larger preoperative lesions (≥22.828 cm³) with smaller ones (<22.828 cm³). (E) RFS analysis comparing gross total resection with subtotal resection. (F) P-value heatmap showed statistically significant clusters after comparing gross total resection with subtotal resection. The color ranging from green to dark blue, and bright yellow to red, both indicated the p-value from 0.05 to 0.0001.
