Across 3 studies, no beneficial effects of vitamin C on reducing hospital stay were observed; all studies reported neutral effects with small effect sizes.
Caveats: Evidence base is small (only 3 studies) — conclusions should be considered preliminary. Many of the included studies did not reach statistical significance — effect may be smaller than the predominant direction suggests.
Adverse effects were minimal, with isolated incidents of nausea, vomiting, hypotension, and tachycardia reported.

the white blood cell count, length of hospital stay, postoperative nausea and vomiting, and postoperative complications were not significantly different between the two groups.
Secondary outcomes, including hospital length-of-stay (LOS), intensive-care-unit (ICU) LOS, and mechanical ventilation, exhibited mixed results. Notably, heterogeneity and publication bias were observed in hospital LOS analysis, necessitating cautious interpretation.
