Mean PER was lower (2.16 vs 2.56\u2009mmol\/h; <jats:italic>P\u2009=<\/jats:italic>\u20090.03) and occurred earlier (17.6 vs 23.2\u2009h; <jats:italic>P\u2009=<\/jats:italic>\u20090.13) for the new regimen.

The new regimen had shorter period of hypocalcaemia (28.9 vs 66.4\u2009h, <jats:italic>P\u2009=<\/jats:italic>\u20090.04), and required less calcium infusion (67.7 vs 127.2\u2009mmol, <jats:italic>P\u2009=<\/jats:italic>\u20090.02) for a shorter duration (57.3 vs 102.9\u2009h, <jats:italic>P\u2009=<\/jats:italic>\u20090.001).
