Factors Associated with Dengue Shock Syndrome: A Systematic Review and Meta-Analysis
Figure 2
Meta-regression analysis between the proportion of DSS among DHF/DSS cases and year of recruitment.
All studies (A). Sub-regression analysis of all studies except three studies in South America (B), 49 studies in Southeast Asia (C), 16 studies in South Asia (D), seven studies in Caribbean countries (E), and 23 studies in Thailand (F). The logit event rate was calculated as follow: logit event rate = ln[event rate/(1 − event rate)]. The Y-axis on the right shows the proportion of DSS patients amongst DHF/DSS patients. Each circle represents a data set in the meta-analysis, and the size of the circle is proportional to study weighting.
