Fig. 1From: Association of different pathologic subtypes of growth hormone producing pituitary adenoma and remission in acromegaly patients: a retrospective cohort studyThe overall rate of postoperative remission, response to medical treatment, according to the pathological subtypes. Remission criteria were defined as the IGF-1 normalization, adjusted to age, sex, and GH levels below 1 ng/ml, 3–6 months after surgery [29, 30]. Medical tx refers to the response to first generation-SRL assessed 3–6 months after starting medication by IGF-I levels and classified in three different groups. Full responders, defined as normal age-matched IGF-I levels; partial responders, defined as IGF-I reduction ≥50% from baseline but without normalization; poor responders, defined as IGF-I reduction of < 50% from baseline [31]Back to article page
