NA indicates not available (the SHPM is clearly the best expected model).

*

Maximum likelihood estimate of the HSC frequency obtained on fitting the SHPM to the data.

SE(fc1) indicates conditional standard error of fc1; based on standard normal distribution of fc1 95% CI (fc1) is given by the endpoints fc1 ± 1.96 × SE (fc1).

Value(s) of C corresponding to the set P of plausible C≥1PMs, C being the minimum number of HSCs necessary to promote detectable repopulation in recipients (positive outcome).

§

indicates the C≥1PM model–averaged HSC frequency estimate in the set P of plausible C≥1PMs.

SE () indicates the unconditional standard error of ; 95% CI () is given by the endpoints ±1.96× SE (); see supplemental data.
