Although the proportion of severe lymphopenia (<500/μL) was 62.1% at day-7 before LT and almost half (48.3%) at one month after LT in PTH-NLR recipients, only the pre-LT lymphocyte count was observed in this study as a prognostic factor in liver transplant recipients as described in Nagai’s previous study [17]. Here, PTH is linked to lymphopenia.
