Is low platelet count associated with ductus arteriosus patency in preterm newborns?
PDA was associated with low platelet count and high PDW but not with other platelet indices in preterm infants. We could not show an association between platelet counts and persistence or closure after medical treatment.
In a cohort of statin initiators identified using prescription claims, 20% had evidence of statin possession during the baseline period. Pharmacoepidemiologic new user studies may benefit from including sensitivity analyses within subgroups less likely to include prevalent users to assess the robustness of key findings to misidentification of the time of treatment initiation.
