Additionally, when VAN\/DAP was administered randomly, COMBO was associated with higher all\u2010cause mortality (RR\u2009=\u20091.37, 95% CI: 1.05\u20131.78,\n                    <jats:italic>p<\/jats:italic>\n                    = 0.02) and 30\u2010day mortality (RR\u2009=\u20091.41, 95% CI: 1.01\u20131.96,\n                    <jats:italic>p<\/jats:italic>\n                    = 0.02).

No differences were observed in the microbiological failure rate, duration of bacteremia, or length of hospital stay.

However, it improved microbiological outcomes without raising AKI risk. However, these microbiological advantages must be weighed against two concerning findings: a nonsignificant trend toward increased Clostridium difficile infection (CDI) risk and elevated mortality signals in high\u2010quality subgroup analyses. Given conflicting mortality signals, cautious clinical application and further RCTs are needed.\n
