Extremely low birth weight neonates (30 studies).
Platelet indices in neonates with IVH.
Platelet indices in neonates without IVH.
The meta-analysis showed that at day 1 of life, neither platelet count nor MPV differed significantly between neonates with or without IVH. However, platelet counts < 100 x 10(9)/L were associated with an increased risk of IVH. Secondary hemostasis parameters did not differ between neonates with and without IVH. Fibrinolysis was only sparsely investigated.
