Pediatric Increased Risk and Nonlinear Age-Dependent Risk of Hypoparathyroidism After Total Thyroidectomy: A 1914-Patient Cohort Study.
Article in World journal of surgery, 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
backgroundPost-thyroidectomy hypoparathyroidism is the most common complication of total thyroidectomy and a key indicator of surgical quality. The influence of age on postoperative risk, across the spectrum from pediatric to adult patients, remains incompletely defined.
methodsRetrospective cohort study of 1914 consecutive patients undergoing primary total thyroidectomy for Graves' disease or differentiated thyroid carcinoma at a high-volume center, comprising 87 pediatric (< 18 years) and 1827 adult (≥ 18 years) patients operated on by the same endocrine surgical team. Transient and permanent hypoparathyroidism were defined according to the 2025 ESES/AAES/IAES consensus, with permanent disease confirmed biochemically beyond 12 months. Multivariable models were adjusted for surgical indication and lymph node dissection; within adults, age was modeled with restricted cubic splines followed by an age-band analysis. Pediatric histopathology was reviewed for inadvertent parathyroid excision.
resultsTransient hypoparathyroidism occurred in 29.9% of pediatric and 17.2% of adult patients (P = 0.004) and permanent hypoparathyroidism in 3.4% and 0.4% (P = 0.011). After adjustment, pediatric age remained independently associated with transient (OR 1.86, 95% CI 1.15-3.01) and permanent hypoparathyroidism (OR 5.74, 95% CI 1.35-20.02). Other surgical complications did not differ between groups. Inadvertent parathyroid excision was uncommon and accounted for only 1 pediatric hypoparathyroidism case, implicating devascularization rather than gland removal. Among adults, age showed a non-linear association with transient hypoparathyroidism, with increased risk at 40-50 years (OR 1.50, 95% CI 1.15-1.96; P = 0.003), particularly in differentiated thyroid carcinoma.
conclusionsPediatric patients undergoing primary total thyroidectomy are at increased risk of postoperative hypoparathyroidism independent of surgical indication and extent, even under uniform high-volume surgical conditions, with devascularization the likely mechanism. In adults, risk varies non-linearly with age. These findings support age as a determinant of postoperative endocrine outcomes.
