CRSR-FAST Accuracy and Precision

Measure	Formula	Value	SE^*
True positive rate $(T P R)$ , Sensitivity	$\frac{T P}{T P + F N}$	0.81	0.07
True negative rate $(T N R)$ , Specificity	$\frac{T N}{T N + F P}$	0.89	0.08
Accuracy	$\frac{T P + T N}{T P + T N + F P + F N}$	0.84	0.05
Positive predictive value $(P P V)$	$\frac{T P}{T P + F P}$	0.92	0.06
Negative predictive value $(N P V)$	$\frac{T N}{T N + F N}$	0.76	0.09
False positive rate $(F P R)$	$\frac{F P}{F P + T N}$	0.11	0.08
False discovery rate $(F D R)$	$\frac{F P}{F P + T P}$	0.08	0.06

Bootstrap method, 1000 samples

TP, True Positive: number of times both CRS-R full and CRSR-FAST ratings indicate “conscious”

TN, True Negative: number of times both CRS-R full and CRSR-FAST ratings indicate “not conscious”

FP, False Positive: number of times CRS-R full rating is “not conscious” and CRSR-Fast rating is “conscious”

FN, False Negative: number of times CRS-R full rating is “conscious” and CRSR-Fast rating is “not conscious”

SE, Standard Error
