• Some patients achieved glycemic control with the initial 14 units of basal insulin.
• Other patients required substantial escalation of the basal insulin dose.
• The variation reflected differences in the degree of insulin resistance among patients with GDM.
• Figure 1 compares initial and peak basal insulin requirements within the cohort.
• The horizontal line in each boxplot indicates the median.
• The box represents the interquartile range from the 25th to the 75th percentile.
• The whiskers extend to 1.5 times the interquartile range.
• Dots represent outlying observations.
