We retrospectively reviewed 2407 adult patients with acute myeloid leukaemia who underwent their first related PBSCT between 2000 and 2019. The median infused CD34\n                    <jats:sup>+<\/jats:sup>\n                    cell dose was 3.67\u2009\u00d7\u200910\n                    <jats:sup>6<\/jats:sup>\n                    \/kg.

The 5\u2010year overall survival rates were 37.2%, 40.2% and 37.4% in the low, intermediate and high groups respectively (\n                    <jats:italic>p<\/jats:italic>\n                    \u2009=\u20090.176). Although the high\u2010group patients experienced faster neutrophil engraftment, cumulative incidences of infection and primary engraftment failure were comparable across groups. Platelet engraftment was significantly delayed in the low group, with 21.7% failing to engraft at day 100, compared to 14.6% and 13.4% in the intermediate and high groups (\n                    <jats:italic>p<\/jats:italic>\n                    \u2009&lt;\u20090.001).
