From: Evaluation of a method to measure HHV-6B infection in vitro based on cell size

Size measurement approach Size of individual cells Average size
Infection day (dpi) 4 7 4 7
Cutoff value (μm)a 13.9 14.3 (13.9) 14.2 (13.5) 13.5
Sensitivityb 0.77 0.66 (0.69) 0.93 (0.96) 1.00
False negativesc 23% 34% (31%) 7% (4%) 0%
Specificityb 0.87 0.91 (0.87) 1.00 (0.96) 0.96
False positivesc 13% 9% (13%) 0% (4%) 4%
  1. aCutoff value for maximized product of sensitivity and specificity for each size measurement approach and infection day (dpi); in parenthesis, a consensus cutoff value for each size measurement approach is shown. bSensitivity and specificity at each cutoff value; in parenthesis, sensitivity and specificity associated with the consensus cutoff values. cPercentage of false negatives and false positives at each cutoff values; in parenthesis, values for consensus cutoff values
