Fig. 3From: Retrospective analysis of insulin responses to standard dosed oral glucose tests (OGTs) via naso-gastric tubing towards definition of an objective cut-off valuePseudomedian (solid line) and 95% confidence interval (dashed line) of the insulin response in oral glucose test (OGT) for both clusters (cluster 1—dark blue; cluster 2—light blue). As the distribution of the insulin levels in each cluster for each time-point are not normal, the median was chosen as a better representation of how the insulin response differs between the clustersBack to article page
