In OCT, BRS struts remained detectable in all 48 BRS. Normalized light intensity as a marker for the resorption of BRS struts increased with time in a linear fashion (Spearman Rho: <jats:italic>p<\/jats:italic> &lt;\u2009.001, correlation coefficient\u2009=\u2009.90; <jats:italic>R<\/jats:italic><jats:sup>2<\/jats:sup> [linear]\u2009=\u2009.91).
