Characterization of Unilateral Adrenal Incidentalomas: Hormonal Analysis, Computed Tomography, and Magnetic Resonance Imaging Correlation.

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
introductionAdrenal incidentalomas are adrenal masses detected on imaging performed for reasons other than suspected adrenal disease. Although most adrenal incidentalomas are nonfunctioning adenomas, some require treatment, particularly hormonally active or malignant lesions.
objectiveThe purpose of this study was to analyze the clinico-hormonal and radiological characteristics of adrenal incidentalomas, to determine radiological features predictive of malignancy, and to compare nonfunctioning and cortisol-secreting adenomas in terms of radiological features.
methodsThis study involved 153 adult patients diagnosed with adrenal incidentaloma between 2015 and 2023. Clinical, hormonal, and imaging data were collected for all participants.
resultsThe mean age of patients was 55 ± 13 years. Autonomous cortisol secretion was the most common hormonal activity, observed in 17% of cases, while 73.85% of patients had non-functional tumors. The most frequent diagnosis was adenoma, identified in 80.4% of patients. Adrenocortical carcinoma and pheochromocytoma were each diagnosed in 3.9% of patients. The mean size was significantly greater in adrenocortical carcinoma cases than in lipid-poor adenomas (61 ± 27.07 mm vs. 26.97 ± 11.85 mm; p = 0.027). The mean non-contrast CT density of adrenocortical carcinoma was 29.7 Hounsfield units, with a range of 18 to 41. Furthermore, cortisol-secreting adenomas were significantly larger than non-secreting adenomas and were more often lipid-poor. Contralateral adrenal atrophy and hepatic steatosis were significantly more prevalent in cortisol-secreting adenomas compared to non-secreting adenomas: (26.1% [n = 6] vs. 1.1% [n = 1]; p < 10⁻³) and (47.8% [n = 11] vs. 18.1% [n = 17]; p = 0.003), respectively.
conclusionsWe examined the clinical, radiological, and hormonal profiles of patients with adrenal incidentalomas, finding results consistent with existing literature. The main etiology in our series was a non-functioning adrenal adenoma. Autonomous cortisol secretion is the most prevalent hormonal activity. Imaging played a key role not only in distinguishing benign from malignant lesions but also in identifying features suggestive of cortisol secretion.
