In a recently published article (Kanaan NC, Peterson AL, Pun M, et al. Prophylactic acetaminophen or ibuprofen result in equivalent acute mountain sickness incidence at high altitude: a prospective randomized trial. Wilderness Environ Med. 2017;28:72–78. http://dx.doi.org/10.1016/j.wem.2016.12.011), an error was made in the title, failing to use the singular form of the verb: “results.” The correct form is Prophylactic Acetaminophen or Ibuprofen Results in Equivalent Acute Mountain Sickness Incidence at High Altitude: A Prospective Randomized Trial.
