NTHi dominance in oropharyngeal swabs of healthy adult (18–65 years) or elderly (>65 years) participants co-colonised with Hh. NTHi oropharyngeal carriage prevalence (A) or proportion of NTHi (as a function of total Hh) (B) among participants concurrently carrying Hh strains that possess the hpl ORF (Hh-hpl+) or do not possess the hpl ORF (Hh-hpl−). Hh-hpl+ (predominant) denotes instances where hpl+ is the predominant Hh genotype (>0.5 of total Hh). Error bars represent ±SEM; statistical significance was determined by simple logistic regression (A) or nonparametric Spearman correlation (B); ** p < 0.005, *** p < 0.001, **** p < 0.0001.
