Figure 2From: A comparison of the sensitivity of EQ-5D, SF-6D and TTO utility values to changes in vision and perceived visual function in patients with primary open-angle glaucoma Median (IQR) of EQ-5D, SF-36 and TTO UVs by IVF quartile. Q-5D = UVs derived using EuroQoL tool. SF-6D = UVs derived from SF-36 using SF-6D algorithm [53]. TTO = time trade-off utility value.Back to article page
