Objective

To measure the effects of a summary-of-findings (SoF) table on user satisfaction, understanding, and time spent finding key results in a Cochrane review.

Study Design and Setting

We randomized participants in an evidence-based practice workshop (randomized controlled trial [RCT] I) and a Cochrane Collaboration entities meeting (RCT II) to receive a Cochrane review with or without an SoF table. In RCT I, we measured user satisfaction. In RCT II, we measured correct comprehension and time spent finding key results.

Results

RCT I: Participants with the SoF table (n = 47) were more likely to “agree” or “strongly agree” that it was easy to find results for important outcomes than (n = 25) participants without the SoF table—68 % vs. 40 % (P = 0.021). RCT II: Participants with the SoF table (n = 18) were more likely to correctly answer two questions regarding results than (n = 15) those without the SoF table: 93 % vs. 44 % (P = 0.003) and 87 % vs. 11 % (P < 0.001). Participants with the SoF table spent an average of 90 seconds to find key information compared with 4 minutes for participants without the SoF table (P = 0.002).

Conclusion

In two small trials, we found that inclusion of an SoF table in a review improved understanding and rapid retrieval of key findings compared with reviews with no SoF table.
