Adrenal recovery over time. Abbreviations: AI adrenal insufficiency; GC, glucocorticoid; d, day; w, week; y, year. Each point represents a study in which HPA-axis tests were repeated at least once following withdrawal of GC therapy (in all patients, in patients with AI at the initial test, or in a subset of the latter). Horizontal axis: time between the final GC dose and the final test performed during the study. Vertical axis: percentage of patients found to have AI at the final test. Points are labeled with the total number of patients retested during the studies, including those who did and did not recover by the end of follow-up. The size of the point reflects the number of patients retested.
