MUC5B and susceptibility to pneumonia measurement: The pooling results in Table 4 show a significant association between MUC5B rs35705950 and high susceptibility to pneumonia in the overall population under the genetic models of allelic T vs. G (OR = 3.78), carrier T vs. G (OR = 3.31), TT vs. GG (OR = 13.66), GT vs. GG (OR = 4.78), GT + TT vs. GG (OR = 5.05), and TT vs. GG + GT (OR = 6.47) (all Passociation < 0.001, Bonferroni-Passociation < 0.006; FDR-Passociation < 0.0010).
