Risk factors of renal complications in childhood-onset non-surgical hypoparathyroidism: a long-term follow-up study.
Article in Endocrine, 2026. 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
contextIt is unclear about the prevalence and risk factors of renal complications in childhood-onset patients with non-surgical hypoparathyroidism (ns-HP), which significantly hinders the clinical management and prognosis improvement.
objectiveTo investigate the prevalence and risk factors of chronic renal complications in childhood-onset ns-HP patients receiving conventional therapy. DESIGN AND
settingA retrospective cohort in childhood-onset patients with ns-HP at a tertiary care center, between 1977 and 2022. PATIENTS AND
methodsChildhood-onset ns-HP patients who received conventional treatment and were followed for at least 1 year were enrolled. Kaplan-Meier survival analysis and Cox regression were performed to identify the risk factors of renal complications. Time-dependent ROC curves were utilized to explore their optimal cutoff values.
resultsA total of 143 patients were enrolled in our cohort. Excluding 6 cases with pre-existed RC, 29/137 (21.17%) cases developed renal calcification (RC) during follow-up of 11.5 ± 8.5 years. Compared with patients without RC, they had a higher proportion of hypercalciuria (52.69 ± 32.8% vs. 35.64 ± 25.84%, P = 0.015) and renal insufficiency (RI) (17.24% vs. 3.70%, P = 0.021). Serum calcium-phosphate product (Ca×PO4) (HR = 1.205, P = 0.033) and hypercalciuria proportion (HR = 1.048, P = 0.043) were independent risk factors for RC, with optimal cutoffs of 41.96 mg²/dL² (AUC = 0.735) and 60% (AUC = 0.697), respectively. RI occurred in 6.29% (9/143) of patients, and the highest serum TCa during treatment (HR = 7.277, P = 0.019) was the risk factor of RI.
conclusionTo reduce RC risk in childhood-onset ns-HP patients on conventional treatment, it is essential to consistently control the serum Ca×PO₄ and urinary calcium excretion. Hypercalcemia during the treatment should be avoided to prevent RI.
