Erratum to: Feasibility trial for primary stroke prevention in children with sickle cell anemia in Nigeria (SPIN trial) (American Journal of Hematology, (2017), 92, 8, (780-788), 10.1002/ajh.24770)

We wish to formally correct the above-referenced article and omit mention utilization of the Morisky medication adherence scale. The Morisky medication adherence scale was used to access study participants adherence on a monthly basis by parental recall.We did not realize that the questions were protected by copyright and required permission for utilization. For the duration of the study, the adherence tool is used as a secondary measurement of adherence, while the primary indicator included change in mean cell volume. The removal of the Morisky scale adherence data does not affect the primary outcomes of the study and does not alter the evidence of adherence, because increase in MCV was the primary measure of adherence. All the authors of the manuscript have been informed of the changes and have agreed to the publication of an erratum. We apologize for any inconvenience that this error might have caused.
