Prediction of early biochemical and symptomatic hypocalcemia in thyroid cancer patients after total thyroidectomy.
Article in Endocrine, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
purposeHypocalcemia is a common complication after total thyroidectomy (TT). Several studies have identified risk factors for early biochemical hypocalcemia, nevertheless, the noteworthy symptomatic hypocalcemia has not been considered. This study aims to construct an intuitive predictive model for biochemical and symptomatic hypocalcemia to assist individualized management.
methodsA retrospective study was conducted on thyroid cancer patients undergoing TT. Two separate patient cohorts were used for model development and external validation, respectively. Data were gathered to identify the risk factors for biochemical (serum calcium <8.0 mg/dL) and symptomatic hypocalcemia by logistic regression. A predictive model was visualized by a nomogram and validated internally and externally.
resultsOf 431 patients studied, 258 (59.9%) developed hypocalcemia including 180 with biochemical hypocalcemia and 196 with symptomatic hypocalcemia, of whom 118 patients had both. Female (OR 2.108, 95% CI 1.166-3.812, P = 0.014) and postoperative PTH decreased ratio ≥ 60% (OR 22.489, 95% CI 13.289-38.058, P < 0.001) were independent risk factors for hypocalcemia, while BMI ≥ 24 kg/m
conclusionThe validated nomogram combining gender, BMI and proportion of PTH reduction may guide the risk identification and stratified management of hypocalcemia after total thyroidectomy.
