Accuracy of the algorithms variants vs. the Emilia-Romagna Dialysis (ERDR) registry

	Algorithm using only ASV data	Algorithm 1 with 60 days’ threshold	Algorithm 1 with 90 days’ threshold	Algorithm 2 with 60 days’ threshold	Algorithm 2 with 90 days’ threshold
Incident cases identified by the algorithm	637	697	683	711	690
Found in ERDR, incident in 2014	534	550	542	538	531
Found in ERDR, incident in a different year	55	67	67	51	49
Not found in ERDR	48	80	74	122	110
Incident ERDR cases in 2014 missed by the algorithm	88	75	82	84	90
Percentage agreement	73.7%	71.2%	70.8%	67.7%	68.1%
Sensitivity	85.9%	88.0%	86.9%	86.5%	85.5%
