Post-operative hypocalcaemia was associated with higher pre-operative ALP (p = 0.001), with total PTx (p = 0.03) and with female gender (p = 0.04), but there were no significant associations with age, dialysis vintage, pre-operative serum calcium, phosphate, PTH, history of fracture, use of anti-resorptive medications or cinacalcet use. Here, PTH is linked to Hypocalcemia.
