For ICU admission, the primary analysis showed a trend toward a lower probability of admission in the group of interest (OR = 0.39; 95% CI: 0.15–1.00; p = 0.051).
Similarly, other antibiotics such as chloramphenicol (OR 0.22), cloxacillin (OR 0.28), cephalosporins (OR 0.32), and levofloxacin (OR 0.35) also showed ORs less than 1, indicating lower susceptibility by serotype 19A, although this difference did not reach statistical significance.
