|Summary of Findings
|From 4360 Cochrane plain language summaries of interventional studies published from 1995 to 2019. Most of the plain language summaries (80%) did not have a conclusive message. In 53% plain language summaries there was no concluding opinion about the studied intervention or the conclusion was unclear. The most frequent conclusiveness category was “no opinion” (30%), and its frequency increased over time. The median number of years of non-specific education needed to read the plain language summaries was 14.9 (IQR 13.8 to 16.1), indicating that the person needs almost 15 years of general education to read the content with ease.
