The HI-score was higher in PRA than in TLA (97 vs 46, <jats:italic>p<\/jats:italic>\u2009&lt;\u20090.001) due to more frequent (IQR: 2\u20135 vs IQR: 1\u20133, <jats:italic>p\u2009<\/jats:italic>=\u20090.025) and longer episodes of hypotension (5.6% vs 7.1%, <jats:italic>p<\/jats:italic>\u2009=\u20090.013), and longer episodes of bradycardia (9.9% vs 16.9%, <jats:italic>p<\/jats:italic>\u2009=\u20090.038).
