Fig. 2

Box and whisker plots showing percentage eGFR change from baseline to follow-up for all subjects (a) and stratified according to level of eGFR (b) and hypercalcemia (c). Upper and lower part of the box represents interquartile range (25,75%) with median shown as the line within the box and whiskers shows 5 and 95% percentiles. PTX-treated had a statistically significant higher percentage eGFR change compared to non-PTX treated (* = p < 0.05). Abbreviations: eGFR: estimated glomerular filtration rate; PTX: parathyroidectomy. aFootnote: Mild hypercalcemia is defined as plasma levels of ionized calcium above upper limit of normal but below 1.45 mmol/L. Moderate to severe hypercalcemia is defined as ionized calcium levels ≥1.45 mmol/L.
