Table 1. ANCOVA of translation efficiency on NMD with (a) folding free energy centered at −4 and (b) initiation codon adaptation index as a covariate, respectively
CoefficientaP‐value
(a) Folding free energy
 Folding free energy centered at −40.060292<2e−16
 NMDb−1.074439<2e−16
 Intercept−1.50631<2e−16
(b) Initiation codon adaptation index
 Initiation codon adaptation score0.606686.14E−11
 NMDb−1.06463<2e−16
 Intercept−1.95885<2e−16
  • a Coefficient is the raw values and not comparable among variables.

  • b In the model, NMD and non‐NMD were given 1 and 0, respectively. Thus, a negative coefficient means NMD group has smaller values.
