The objective of this study is to evaluate the efficacy of infographics, compared to standard PLS and scientific abstract format, in presenting information, in terms of understanding and remembering research results by physicians.
The investigators will conduct a randomized controlled trial (RCT) with three different formats of the same systematic review summary (Infographics, PLS, scientific abstract). The content of these three formats is based on the same systematic review, but the ways of data presentation will differ: visual presentation in plain language, plain language only, and text with scientific abbreviations. The interventions will be delivered online in January 2016, with physicians who are currently working at Clinical Hospital Split. The trial will be preformed online, and it will be voluntary and anonymous. The survey will consist of 5 parts, in the following order: 1) one format of the summary (randomly assigned), 2) health numeracy, 3) demographic data 4) comprehension test of the information given in the summary, and 5) user friendliness of information and overall satisfaction with the given summary assessed by survey.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| PLS | Active Comparator | The control group will receive PLS: text format with simple explanation of the survey topic main findings and is intended for lay audience. |
|
| Infographics | Experimental | Infographics format of a Cochrane systematic review summary represents the experimental intervention in the trial, where the results are presented with text and pictures. |
|
| Scientific abstract | Active Comparator | Scientific abstract is the text written for the academic population and practitioners. It is also intended for control group. |

| Understanding of the Content of Summary Format | The questions will focus on understanding the benefits and risks of the intervention and the quality of evidence described in the systematic review. In total, there will be 10 open ended questions, and the total score will be the sum of the correct answers (minimum 0, maximum 10). Higher scores would indicate higher understanding. | One month (30 days) |
| Measure | Description | Time Frame |
|---|---|---|
| Reading Experience | This section of the survey will include 5 questions about the experience of participants about the text they read, measured on a 10-point Likert type scale, where 1 means do not agree at all and 10 means fully agree. The total score is the sum of scores on all five answers (minimum 5, maximum 50). Higher scores would indicate higher, or more positive, reading experience. | One month (30 days) |
| Measure | Description | Time Frame |
|---|---|---|
| Health Numeracy | This section will use 6-item General health numeracy test (Osborne et al., 2013) in order to determine how much our participants understand the basic health instructions regarding numeracy dimension. For each correct answer, the participants receive one point and the total score is the sum of all correct answers. | One month (30 days) |
