Table 4.

The entries in this table describe the steps taken each day in the simulation of KPD only or KPD + DD strategies

Simulated daily procedures
a	Some pairs withdraw from KPD pool.
b	New pairs and nondirected donors arrive in KPD pool.
c	If method “KPD only” is adopted, skip this step. Otherwise, if a DD is eligible to be a DD-CIK, assign one DD kidney to a KPD pair by one of the strategies described in Figures 2, S1–S6.
d	Remove transplanted KPD candidates from the KPD pool and convert the living donor at the end of the DD-initiated chains to a bridge donor.
e	When a match run is due, conduct one as in Table 3.
f	Execute viable transplants selected in previous match runs and return the untransplanted pairs, nondirected donors, and bridge donors to the KPD pool.
g	Allocate bridge donors to a DD candidate on the waitlist if the bridge donor’s idle time surpasses a specified time limit.

DD, deceased donor; DD-CIK, deceased donor chain-initiating kidney; KPD, kidney paired donation.
