marginally nonsignificantP = 0.087
This increased fragility was marginally nonsignificant in 2 K (9/70 vs. 18/70; chi-squared test, P = 0.087) but pronounced in 15 K (9/70 vs. 27/70; P = 0.001), partly driven by 15 K’s increased susceptibility to bile salts (BS) and oxidative (OX) stress ( Fig. 2 F ), the most altered traits ( Fig. 2 D ).
