Benign Adrenal Adenomas Are Associated With Reduced Prevalence of Hospitalised Patients With COVID-19.
Article in Clinical endocrinology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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 (AI) are commonly found on imaging done for indications other than to assess the adrenal glands. Prevalence increases with age and is around 10% in people over 80 years. The majority of AIs are benign adenomas, with 20%-50% exhibiting mild autonomous cortisol secretion (MACS). Clinical guidelines recommend the use of dexamethasone to improve outcomes in patients with COVID-19 requiring oxygen. HYPOTHESIS: Benign adrenal adenomas protect against severe COVID-19.
methodsReports for all computed tomography pulmonary angiogram (CTPA) scans at Sheffield Teaching Hospitals between 11 March 2020 and 10 November 2021 were assessed for details of AI. Scan requests mandated recording COVID-19 status. Patients with a positive COVID-19 test within 2 weeks before the CTPA were classed as COVID-19 positive for the analyses. Duplicate scans were removed.
resultsA total of 4307 CTPA scans were included. The median age was 65 (IQR 49-77) and the majority of patients were female (55.0%). Seventy-six (1.76%) patients had a benign adenoma. COVID-19 positivity was found in 897 (20.8%). The presence of a benign adenoma was associated with a 70% reduced odds of being COVID-19 positive (aOR 0.30, 95% CI 0.12-0.74, p = 0.01), adjusting for age and sex.
conclusionPrevalence of adrenal adenoma was associated with significantly reduced odds of being SARS-CoV2 positive in an inpatient cohort. Secretion of mild excess cortisol (MACS) may be protective against developing severe COVID-19.
