A higher positive correlation between P levels and SAGIT scores was observed both in preoperative acromegaly patients and 1-year postoperative non-remission patients than the correlations between other factors such as GH, OGTT-GH, IGF-1, IGBP-3, IGF-1/IGBP-3, and SAGIT scores, but there was no correlation between hyperphosphatemia and remission rates [2]. Here, IGF1 is linked to acromegaly.
