High prevalence of hyperuricemia and its risk factors in a Chinese cohort of primary hyperparathyroidism patients.
Article in Endocrine, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
purposePrimary hyperparathyroidism (PHPT) is characterized by autonomous and excessive parathyroid hormone (PTH) secretion due to parathyroid gland lesions. Patients can be complicated with hyperuricemia (HUA), however, data about HUA in Chinese PHPT patients are lacking. This study aimed to explore the prevalence of HUA, factors influencing serum uric acid (SUA) level and the impacts of parathyroidectomy (PTX).
methods328 inpatients diagnosed with PHPT were included in total. Clinical data were collected and compared between HUA and non-HUA group. Multivariate linear regression was used to explore the factors affecting preoperative SUA and its variation after PTX. The impacts of SUA on bone mineral density (BMD) under different models were also analyzed.
resultsThe prevalence of HUA in PHPT patients was nearly 32%. Compared with non-HUA group, HUA group had significantly higher serum calcium (Ca) (2.92 [2.75, 3.26] vs. 2.78 [2.62, 3.03] mmol/L, P < 0.001), while PTH increased without significance. Gender, body mass index, serum Ca, triglycerides and renal function were independently associated with SUA. SUA decreased after PTX (340.00 [291.50, 421.00] vs. 315.00 [270.50, 375.00] μmol/L, P = 0.018), with change of SUA significantly associating with changes in serum Ca and phosphate. Presurgical SUA was positively related with femoral neck, total hip and lumbar spine BMDs after adjusting for confounders.
conclusionA relatively high proportion of HUA was found in our study. Besides the common risk factors, hypercalcemia may contribute to the increased SUA in PHPT patients, which could be significantly improved by curative PTX. SUA might have a protective effect on bone loss in PHPT patients.
