ATECNP (atezolizumab with carboplatin and nab-paclitaxel), ATECP (atezolizumab with carboplatin and paclitaxel), ATEBEVCP (atezolizumab with bevacizumab, carboplatin, and paclitaxel), and ATE (atezolizumab monotherapy). Forest plot of the adjusted association between antibiotic use and prognosis by study arm in the cohort randomised therapies with atezolizumab. Median time to progression-free survival (PFS) and overall survival (OS) are unadjusted. (A) Forest plot of association of antibiotics with PFS. (B) Forest plot of association of antibiotics with OS. (C) Forest plot of association of antibiotics with objective response rate (ORR).
