No studies reported measurement error. Criterion validity was not evaluated as there is no measurement “gold standard.”
NR: not reported. N/A: not applicable
GRADE: Grading of Recommendations Assessment, Development, and Evaluation; SF-36: 36-item Short Form Survey; PAS: Parathyroidectomy Assessment of Symptoms; PHPQoL: Primary Hyperparathyroidism Quality of Life
