^aDeath (n = 19), alternative dialysis modality (n = 3), lost to follow-up (n = 5).

^bDeath (n = 8), alternative dialysis modality (n = 6), lost to follow-up (n = 2), never started dialysis (n = 24).

^cMedian follow-up, 26 months (interquartile range, 17-37 months).

^dMedian follow-up, 28 months (interquartile range, 18-39 months).
