Preoperative phosphorus levels may serve as a predictor of recurrent/persistent lesions after surgery for primary hyperparathyroidism: a cross-sectional study.

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
Background: Surgery is the definitive treatment for primary hyperparathyroidism (PHPT). However, surgical outcomes can be affected by numerous factors, some of which are still a matter of debate. We examined cases at the First Affiliated Hospital of Zhejiang University, and assessed the risk factors affecting surgical success and postoperative recurrence. Methods: We conducted a retrospective analysis of the clinical data of patients who underwent surgery for PHPT without intraoperative parathyroid hormone (IOPTH) monitoring at the First Affiliated Hospital of Zhejiang University between August 2017 and June 2022. We analyzed the surgical success rates, recurrence rates, and persistent disease rates, and performed univariate and multivariate analyses to identify the risk factors associated with surgical success and postoperative recurrence/persistent lesions. Results: The overall surgical success rate was 97.8%, and the postoperative recurrence rate was 8.2%. Univariate analysis confirmed that a higher level of preoperative parathyroid hormone (PTH) and blood calcium is associated with a lower success rate of surgery (P<0.05). However, the multivariate analysis did not reveal any significance in them. The univariate analysis identified preoperative target organ damage, urolithiasis, and preoperative alkaline phosphatase (ALP), PTH, and phosphorus levels as risk factors for postoperative recurrence/persistent lesions (P<0.05). The multivariate analysis revealed that only the phosphorus level was a significant risk factor for postoperative recurrence/persistent lesions (P<0.05). The receiver operating characteristic (ROC) curve analysis indicated that phosphorus levels below 0.865 mmol/L were associated with a higher incidence of recurrence/persistent lesions, and had a sensitivity of 0.718 and a specificity of 0.67. Conclusions: In PHPT, satisfactory surgical success rates can be achieved without IOPTH monitoring. The blood phosphorus level is a significant predictor of postoperative recurrence or persistent lesions, and thus could guide clinical decision making.
