case_images: Blood concentration of calcium, parathyroid hormone (PTH), and vitamin D over five years, B-spline fit.. (A) Calcium concentration; (B) PTH concentration; (C) 25-OH vitamin D concentration. The gray area represents the time atorvastatin was used (atorvastatin administration started in November 2020, stopped in September 2021, renewed in June 2022, and finally stopped in September 2022).

case_images: Periodic blood tests for calcium revealed stable levels, maintaining around 10.8 mg/dL since 2017 (Figure 1A exhibits his calcium concentration over time). Looking at additional tests for a broader period, it is evident that his phosphorus was usually low (ranged between 2.08 and 2.83 mg/dL), his parathyroid hormone (PTH) was usually high (ranged between 44.4 and 95.7 pg/mL) (Figure 1B), and his 25-OH vitamin D was considered mildly low (ranged between 43 and 69 nmol/L) (Figure 1C). Looking at his PTH levels in Figure 1B, it is evident they did not change after receiving atorvastatin, thus weakening this hypothesis. Figure 1A shows the rise and fall of calcium levels after receiving and stopping atorvastatin, respectively.
