participant-visit-listing

The Participant Visit Listing is a JavaScript library that visualizes the schedule of events in a clinical trial for each participant. The library aids in the detection of participant and site compliance issues via a heat map, a longitudinal chart, and a tabular listing.

Displays

The Participant Visit Listing generates three distinct displays of the schedule of events:

Visit Chart

Compact view that provides a quick overview of visit status, even when the number of visits is large.

Study Day Chart

Displays the exact study day for each visit and allows for the inclusion of unscheduled visits. Makes identifying out of window visit trends easy.

    function(data) {
        participantVisitListing().init(data);
    }
);
