In the article by Establishing Sickle Cell Disease Stroke Prevention Teams in Africa is Feasible: Program Evaluation Using the RE-AIM Framework, et al that was published in J Pediatr Hematol Oncol (2022 Jan 1;44(1):e56-e61) many of the references were incorrect.1

Reference Kwaitkowski reference #5 should be number 3; Ware reference #17 should be number 2; Adams RJ reference #4 should be reference #5; Delete Boyd reference #22 in the reference list and text.

New reference #4 and #17

Also the references were incorrect in the following sentences. The correct references are listed.

Page 1- line 9, As a result of standard care practice in high-income countries, the stroke incidence rate has dropped in children with SCA by 10-fold.3,4 Not reference 4, 5.

Page 5- line 3, ∼40 strokes using the number-needed-to-treat to prevent 1 stroke (NNT=7) from the STOP trial and assuming equal efficacy, ∼<1 event per 100 person-years.5 Not reference 4, 17.

Page 1- line 8, After 1 year of regular blood transfusion therapy, hydroxyurea therapy may be used in children without cerebral vasculopathy.2 Not reference 3.

Page 1- line 12, Children with abnormal TCD velocities, ∼20% will have a stroke over 2 years if not treated with regular blood transfusion or hydroxyurea therapy, based on an incidence rate of 10.9 strokes per 100 person-years.5 Not 4, and 5.

Page 2- line 14, On the basis of the STOP protocol.5 Not 4.

Page 2- line 27, The TCD-certified non-radiologist physicians and nurses were also trained and certified on the Pediatric NIH Stroke Scale (PedNIHSS), a validated, standardized neurological examination assessing and quantifying the severity of strokes in children.13 Not 13-15.

Page 2–32. Each participant performed a minimum of 10 observed neurological examinations in children.14,15 No reference was listed and there should be the two references listed.
