Sensitivities, specificities, PPVs, and NPVs of various grades of posterior segment hemorrhage in predicting profound vision loss

Posterior Segment Hemorrhage	Sensitivity (95% CI)	Specificity (95% CI)	PPV (95%CI)	NPV (95% CI)
PSH ≥ grade I	98 (62/63) (91–100)	64 (14/22) (41–83)	89 (62/70) (19–95)	93 (14/15) (68–100)
PSH ≥ grade II	86 (54/63) (75–93)	91 (20/22) (71–99)	96 (54/56) (88–100)	69 (20/29) (49–85)
PSH grade III	78 (49/63) (65–87)	100 (22/22) (85–100)	100 (49/49) (93–100)	61 (22/36) (43,77)

Note:—PSH indicates posterior segment hemorrhage; NPV, negative predictive value.
