How does haptoglobin genotype affect outcomes in aneurysmal subarachnoid hemorrhage?

Takeaway

  • Individual patient level data (IPLD) analysis showed that haptoglobin (HP) genotype is not associated with outcomes after aneurysmal subarachnoid hemorrhage (aSAH).

Why this matters

  • Previous studies have shown conflicting evidence for HP influence on aSAH outcome; a large meta-analysis may provide further information.
