• Retinal microvasculature and masked hypertension in young adults: the African-PREDICT study 

  Ramoshaba, Nthai E.; Huisman, Hugo W.; Lammertyn, Leandi; Schutte, Aletta E.; Smith, Wayne (Springer Nature, 2020)

  Masked hypertension is known to induce microvascular complications. However, it is unclear whether early microvascular changes are already occurring in young, otherwise healthy adults. We therefore investigated whether ...
