The purpose of this Evidence and Gap Map (EGM) is to provide easy access to the available evidence on the effectiveness of interventions to improve functional ability in odler adults.

This EGM includes systematic reviews. This map shows the coverage of 378 systematic review.

In the map the rows are intervention categories and the columns are indicator (outcome) domains. The cells of the table contain a bubble whose size is proportional to the number of studies reporting that outcome for that intervention. There are separate bubbles for systematic review quality, as assessed using the AMSTAR-2 tool. Red color bubbles indicated 'low quality' systematic reviews, orange indicate ‘medium quality’ and green ‘high quality’ systematic reviews. Blue colored bubbles are indicative of EGMs studies.

The map has four version Bubble, heat, donut and mosaic which are self-explanatory. Clicking on a cell gives a list of studies corresponding to an intervention and outcomes for that cell. Click on a study in the list to get publication details, relevant summaries and URL to access the study itself.

The map includes a set of filters like systematic review quality, population, region, countries study design allowing evidence to be shown just for the selected filter. To use this, click the setting tab ‘Filters’ on the top-left of the map. The various categories (filters) can be scrolled down and checked for selection. Once all the relevant filters have been selected, click on ‘Update’.

This EGM also identifies key ‘gaps’, cells which do not have any bubbles, indicates there no evidence from systematic reviews.
