The opening paragraph claimed LGIB had a mortality rate of 2-4% but the cited study was for people aged 60+, and they were divided into 60-85 and 85+ for the study. I found the abstract at http://www.sciencedirect.com/science/article/pii/S0889855305701874 but cannot find the article. I have removed that the mortality rate since it says nothing about age, and even if we know it's for some range 60+ we don't know which age group in the study it refers to, or if it refers to every elderly person. 129.10.18.97 ( talk) 13:18, 14 October 2015 (UTC) reply
