Why the study?
It was unclear which radiological scale estimating the extent of subarachnoid blood has the strongest association with clinical delayed cerebral ischemia after aneurysmal subarachnoid hemorrhage.
Which radiological scale (Fisher, modified Fisher, or Hijdra sum score) has the strongest association with clinical delayed cerebral ischemia in patients with aneurysmal subarachnoid hemorrhage?

All scales associate with DCI; leaves open optimal choice for risk stratification or trial enrichment in aSAH.
Which radiological scale (Fisher, modified Fisher, or Hijdra sum score) has the strongest association with clinical delayed cerebral ischemia in patients with aneurysmal subarachnoid hemorrhage?
The modified Fisher scale may be more suitable than the standard Fisher scale for predicting delayed cerebral ischemia in subarachnoid hemorrhage, as the risk of DCI increases progressively with higher modified Fisher grades.
