![]() Creation and analysis of longitudinal graphs could be used also to inspect other symptoms or clinical problems such as headaches, fatigue, constipation, nausea and vomiting, and psychological difficulties. Discussion:īecause symptoms occur differently for each patient, this method allows researchers to see symptom trajectories on an individual basis. ![]() The steps of VGA include (a) determining inclusion criteria, (b) managing missing data, (c) creating visual graphs, (d) identifying specific patterns, and (e) performing validation and verification. Daily self-reported sore mouth severity scores from patients receiving outpatient chemotherapy were used in this VGA. This methodological article uses data collected from a primary study to present the method of VGA. ![]() To (a) describe the use of VGA as a method to evaluate longitudinal data, (b) discuss challenges to using this method, and (c) offer recommendations for future research in which the method could be implemented. Visual graphical analysis (VGA) is a technique that can provide researchers with an alternative method of quantitative statistical analysis that is more sensitive to individual change and variation. However, typical statistical methods that rely on means can obscure individual trajectories of change. GW Graphical Analysis is part of Vernier’s extensive system of sensors, interfaces and data collection software for science and STEM education.Research to address clinical symptoms and the way they change over time in an individual is of paramount importance to healthcare researchers who are interested in improving the quality of life for ill patients.
