Intraoperative Parathyroid Hormone Monitoring During Parathyroidectomy in Severe Secondary Hyperparathyroidism due to Kidney Failure.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundThe utility of intraoperative parathyroid hormone (IOPTH) monitoring during subtotal parathyroidectomy to predict long-term intact PTH levels in kidney failure remains uncertain.
methodsDiagnostic accuracy study in a cohort of 46 patients with severe, uncontrolled secondary hyperparathyroidism. IOPTH was measured before incision and at 10- and 30-min post-excision. Sensitivity, specificity, and AUC-ROC were assessed for predicting surgical success-defined as iPTH < 300 pg/mL (KDOQI criterion) over 6 months. We also assessed KDIGO criterion as secondary outcome (iPTH < 9× the upper limit of normal, defined as 792 pg/mL) All patients received postoperative calcium and active vitamin D.
resultsSurgical success was achieved in 37 (80%) patients using the KDOQI criterion. Compared with the failure group, the KDOQI success group had lower median 10-min IOPTH (186 pg/mL vs. 495 pg/mL, p < 0.001) and 30-min IOPTH (112 pg/mL vs. 495 pg/mL, p < 0.001). The 10-min percentage decline in IOPTH was also greater in patients who experienced KDOQI success (91% vs. 85%, p = 0.008). AUCs for 10- and 30-min IOPTH in predicting KDOQI success were 0.86 (95% CI: 0.72-1.00) and 0.86 (95% CI: 0.73-1.00), respectively. AUCs for percentage decline at 10 and 30 min were 0.78 (95% CI: 0.63-0.92, p = 0.03) and 0.75 (95% CI: 0.60-0.92, p = 0.02), respectively. A 10-min IOPTH < 270.7 pg/mL yielded 89% sensitivity and 68% specificity for predicting KDOQI success. Using KDIGO criterion, 41 (89%) patients achieved surgical success, with similar trends observed.
conclusionsIn severe secondary hyperparathyroidism due to kidney failure, 10-min IOPTH is a strong predictor of surgical success, with < 270 pg/mL suggesting better outcomes; percentage decline and 30-min values add little benefit.
