AB  - BACKGROUND: Evidence mapping is an emerging tool used to systematically identify, 
      organize and summarize the quantity and focus of scientific evidence on a broad 
      topic, but there are currently no methodological standards. Using the topic of 
      low-calorie sweeteners (LCS) and selected health outcomes, we describe the 
      process of creating an evidence-map database and demonstrate several example 
      descriptive analyses using this database. METHODS: The process of creating an 
      evidence-map database is described in detail. The steps include: developing a 
      comprehensive literature search strategy, establishing study eligibility criteria 
      and a systematic study selection process, extracting data, developing outcome 
      groups with input from expert stakeholders and tabulating data using descriptive 
      analyses. The database was uploaded onto SRDR (Systematic Review Data 
      Repository), an open public data repository. RESULTS: Our final LCS evidence-map 
      database included 225 studies, of which 208 were interventional studies and 17 
      were cohort studies. An example bubble plot was produced to display the 
      evidence-map data and visualize research gaps according to four parameters: 
      comparison types, population baseline health status, outcome groups, and study 
      sample size. This plot indicated a lack of studies assessing appetite and dietary 
      intake related outcomes using LCS with a sugar intake comparison in people with 
      diabetes. CONCLUSION: Evidence mapping is an important tool for the 
      contextualization of in-depth systematic reviews within broader literature and 
      identifies gaps in the evidence base, which can be used to inform future 
      research. An open evidence-map database has the potential to promote knowledge 
      translation from nutrition science to policy.
