marginally significantp = 0.085
Interestingly, the NalRifR702 strain declined faster in the persistence phase than the wt strain ( t -tests, p = 0.032 assuming a power law, or marginally significant if one assumes an exponential decay in the phase, p = 0.085, Table 1 , Figure 3 ), even if these mutations (Nal, Rif, or NalRif) did not affect the decay rate in the persistence phase ( p > 0.05, Table 1 , Figure 2 ).
