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
Introduction: Adrenal incidentalomas are unexpectedly discovered adrenal masses with an estimated prevalence of 8%, often found during imaging for unrelated medical conditions. While primarily benign and hormonally inactive, these lesions have been associated with subtle cortisol autonomy, oxidative stress, and increased cardiovascular risk. The present study investigates the subclinical metabolic and cardiovascular impacts of non-functioning adrenal incidentalomas through oxidative stress and antioxidant marker analysis. Methods: This prospective study included 30 patients with non-functioning adrenal incidentalomas, compared to two control groups: 26 individuals with diabetes mellitus and/or hypertension (HT) and 24 healthy controls matched for age, sex, and body mass index. Hormonal evaluations, oxidative stress markers (malondialdehyde (MDA), nitric oxide (NO), and 3-nitrotyrosine (3-NTx)), antioxidant parameters (superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx), reduced glutathione (GSH), and melatonin), and high-sensitivity C-reactive protein (hsCRP) were assessed. Results: Oxidative stress markers were significantly elevated in patients with adrenal incidentalomas compared to controls (P < 0.001). Antioxidant markers, including SOD, CAT, GPx, GSH, and melatonin, were significantly lower in the case group (P < 0.001). Cortisol levels post-dexamethasone suppression, although within normal limits, were higher in the incidentaloma group, correlating positively with oxidative stress markers (MDA, NO, and 3-NTx) and inversely with antioxidant parameters. Elevated hsCRP levels in the case group indicated a pro-inflammatory state. Conclusions: Non-functioning adrenal incidentalomas are associated with heightened oxidative stress, diminished antioxidant capacity, and systemic inflammation, potentially contributing to cardiovascular and metabolic risks. These findings challenge the assumption that non-functioning incidentalomas are clinically insignificant, emphasizing the need for long-term monitoring and comprehensive evaluation of their systemic effects.
