APTT 10min after locking.
After adjusting for the APTT index prior to tube locking, the APTT levels were found to increase significantly in the heparin group compared to the sodium citrate group at 10 minutes after locking (LSMD = 8.15, 95%CI 7.1 to 9.2, Due to the uneven distribution of catheter insertion location, a post hoc analysis is performed using the internal jugular vein and subclavian vein as subgroups. In the internal jugular vein group, there was a significant increase in APTT levels in the heparin group compared to the sodium citrate group at 10 minutes after tube locking (LSMD = 8.55, 95%CI 6.13 to 10.97,
