**5. Conclusions**

To the best of our knowledge, this is the first study to show that conversion from standard-release Tac to LCPT increases the C/D ratio in LT recipients associated with renal recovery. This finding was independent of known risk factors for renal impairment. Prospective studies are needed to confirm our findings.
