Establishment and validation of a nomogram predicting the risk of osteoporosis with primary aldosteronism.

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
Objective: This study aimed to identify risk factors for osteoporosis (OP) in patients with primary aldosteronism (PA) and to develop a predictive nomogram for estimating OP risk in this population. Methods: We retrospectively enrolled PA patients diagnosed at our hospital between January 2020 and December 2024. The dataset was randomly divided into training (n = 185) and validation (n = 79) sets in a 7:3 ratio. Least absolute shrinkage and selection operator (LASSO) regression combined with multivariate logistic regression was used to identify predictive factors for OP and construct the nomogram. Model discrimination was evaluated using the area under the receiver operating characteristic curve (AUC). Additional performance assessments included the Hosmer-Lemeshow test, calibration curves, and decision curve analysis (DCA). Results: The study included 264 PA patients (mean age 61.2 ± 10.0 years; 110 men, 154 women), with an OP prevalence of 11.4%. LASSO regression identified seven independent predictors: age, sex, body mass index, diabetes history, fasting insulin, plasma aldosterone concentration, and serum creatinine. The nomogram demonstrated strong predictive performance, with AUC values of 0.931 (95% CI: 0.879-0.982) in the training set and 0.842 (95% CI: 0.749-0.935) in the validation set. Calibration curves and DCA confirmed the model's clinical utility. Conclusion: The developed nomogram effectively predicts OP risk in PA patients, offering valuable clinical utility for early identification of high-risk individuals.
