Findings and extraction notes
- The abstract reports no significant benefit for CD4 or CD8 recovery and longer viral-clearance duration among thymosin alpha-1 recipients.
Limitations
- Retrospective treatment allocation is vulnerable to indication and severity confounding.
- The findings do not generalize beyond the studied infection context.
