TGFB1 and hematoma: And, as displayed in Table 3, higher levels of TGF-β1 and TGF-β3 were predictive of poorer long-term functional outcome independent of patient age, hematoma volume, hemorrhage location, admission GCS, and IVH [p = 0.02, OR 1.03 (95% CI 1–1.05) and p = 0.03, OR 3.1 (95% CI 1.1–8.8), respectively].
