Date	Event	Description
9 January 2020	New citation required but conclusions have not changed	No new trials included, but four ongoing trials and one study awaiting assessment, and we found new data for two of the already included trials (WHI 2006; WINS 2006). We updated assessment of risk of bias, including assessment of summary risk of bias for each trial, and carrying out sensitivity analyses omitting trials not at low summary risk of bias. We updated assessment of small study bias by comparing results of fixed‐ and random‐effects meta‐analyses. Data, results, GRADE assessment and conclusions updated.
29 December 2019	New search has been performed	Searches updated to October 2019, searches of trials registers added.
27 March 2015	New citation required and conclusions have changed	We split a previously published review (Reduced or modified dietary fat for preventing cardiovascular disease, DOI: 10.1002/14651858.CD002137.pub3) into six smaller review updates. The conclusions are therefore now focused on reduction in saturated fat intake instead of reducing or modifying fat intake overall on its effect on cardiovascular disease risk. This split review update includes 15 randomised controlled trials.
5 March 2014	New search has been performed	The search has been updated to 5 March 2014.
