In the originally published article there was an error in Table 4. The efficacy of patisiran was incorrectly given as “mNIS+7: 80.9 versus 74.6 with placebo; Norfolk QOL-DN: 59.6 versuss 55.4”; this should read “mNIS+7: 34 points better than placebo; Norfolk QOL-DN: 21.1 points better than placebo”. The “Concerns” of patisiran should also read “Local extravasation may cause irritation”. This has been corrected online, and Table 4 has been corrected below.
