Figure 3. BMI and HB in 99 NPC patients with different PD-1/PD-L1 levels.

Figure 3

(a,b) Statistical analysis suggested no significant (n. s.) differences in the BMI (a) or HB (b) levels between patients with positive or negative PD-1. (c,d) Statistical analysis revealed a significantly lower BMI (c) and HB (d) level in patients with high levels of PD-L1. A t-test was used to evaluate the association of PD1/PD-L1 with BMI and HB level after normality tests and homogeneity of variance test. *P < 0.05.
