简要总结
The investigators will conduct a parallel two-armed, non-inferiority randomized trial comparing new alternative formats of summary of findings tables (SoF) tables with current formats. The investigators will contact Cochrane review users by email and will ask them to fill a questionnaire developed using the "Survey Monkey" online system. The survey will include questions about baseline information (demographic characteristics, background, number of visits to the Cochrane Library, familiarity with the GRADE system, etc.). Then, participants will be stratified (health professional, guideline developer, researcher) and randomly assigned to one of the two SoF table formats, either the alternative (Table A) or the current one (Table C). Participants will be asked to answer questions to determine understanding, accessibility, and satisfaction with the formats to which they were randomized. Finally, the investigators will show them the table format to which they were not initially allocated in order to test their preference for either one.

研究组 & 干预措施
Alternative SoF
Investigators will compare one SoF table with alternative formats (Table A) against one SoF table with the current formats (Table B). In both tables, the clinical question in terms of patients and setting, intervention, comparator, and outcomes informed by the tables, and the complementary information included as footnotes will be the same. The only differences between the current and alternative SoF table formats will be different methods to either show the same data in a different way or to provide complementary data to the one showed in the current format (i.e. supplementary data as risk difference).

Current SoF
Investigators will compare one SoF table with alternative formats (Table A) against one SoF table with the current formats (Table B). In both tables, the clinical question in terms of patients and setting, intervention, comparator, and outcomes informed by the tables, and the complementary information included as footnotes will be the same. The only differences between the current and alternative SoF table formats will be different methods to either show the same data in a different way or to provide complementary data to the one showed in the current format (i.e. supplementary data as risk difference).

结局指标
主要结局
Understanding of key findings
时间窗: 30 minutes
Investigators will frame multiple-choice questions about key concepts in the table with five response alternatives for each question and only one correct answer. Then, investigators will compare the proportion of correct answers between groups per question
次要结局
- Accessibility of information(30 minutes)
- Overall satisfaction(30 minutes)
- Preference(30 minutes)
