Analysis of knowledge loss trend in basic clinical sciences throughout medical education [Letter]

Knowledge retention is a challenge faced by many medical students in undergraduate teaching, and horizontal teaching of preclinical and clinical medicine is a popular curriculum that should be reflected upon. Based on this, we are greatly interested in the study conducted by Zaeemzadeh et al to encourage the vertical integration of basic sciences and clinical sectors.1 Most importantly the authors identified that knowledge loss occurred at all levels after basic sciences were taught, with knowledge loss decreasing as students advanced in their years at medical school. As medical students ourselves, we would like to offer our perspective on the feasibility of the authors' recommendations to promote vertical integration in medical schools
