Fig 7. MATH value and mortality in patients with tumors in the oral cavity or the larynx.

Fig 7

Left, patients with oral-cavity tumors; right, patients with laryngeal tumors. Top, Kaplan-Meier curves for all patients. Blue, low MATH; red, high MATH (MATH > 32). Cox proportional hazards analysis: oral cavity, high/low MATH HR, 1.69 (95% CI, 1.04 to 2.73; p = 0.033); larynx, high/low MATH HR, 3.55 (95% CI, 1.25 to 10.1; p = 0.018). Bottom, joint relation of MATH value and disease stage to survival; dashed, lines Stages I–III; solid lines, Stage IV. Cox proportional hazards analysis: oral cavity, high/low MATH HR, 1.67 (95% CI, 1.03 to 2.70; p = 0.037, Wald test); Stage IV/Stage I–III HR, 1.34 (95% CI, 0.87 to 2.08; p = 0.19); larynx, high/low MATH HR, 3.50 (95% CI, 1.18 to 10.4; p = 0.024); Stage IV/Stage I–III HR, 1.04 (95% CI, 0.44 to 2.49; p = 0.92).
