Figure 4. Forest plots for secondary outcomes, adjusted for covariates, published studies only (HP2-2 vs HP2-1 and HP1-1).
An odds ratio (OR) >1 denotes a higher probability of poor outcome. (A) Delayed cerebral ischemia, (B) radiologic infarction, (C) angiographic evidence of vasospasm, and (D) transcranial Doppler evidence of vasospasm. CI = confidence interval; HP = haptoglobin; ID = identifier.
