Clinical Outcomes and Predictive Factors in Adrenalectomy: A Retrospective Cohort Study.
Article in Iranian journal of pathology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Background & Objective: Adrenal tumors present a notable prevalence of 4-7% in individuals above 40 years old. Current guidelines recommend adrenalectomy for hormone-secreting, potentially malignant, or large (>4 cm) lesions. However, the outcomes of adrenalectomy and their clinical-pathological associations remain poorly defined. This study assessed adrenalectomy outcomes and explored its clinical, demographic, and pathologic correlates. Methods: In this retrospective cohort study, the medical records of all patients who underwent adrenalectomy from March 2016 to March 2021 at a referral center in Tehran were reviewed. Also, a clinical follow-up via telephone was conducted. The chi-square test, independent t-test, and analysis of variance were utilized for statistical analysis. Results: Data from a total of 75 patients (55 females) were reviewed. The mean age of the participants was 42.67 years. Of them, 60%, 22.7%, 14.7%, and 1.3% had pheochromocytoma, Cushing's syndrome, Conn's syndrome, and insulinoma, respectively. Malignancy was associated with greater tumor size (p<0.000) and mitotic rate (p=0.046), and the presence of necrosis (p=0.001), and capsular and vascular invasion (p<0.000). Clinical follow-up visits of 45 patients indicated 84.4% showed a complete response to the treatment (surgical ± medical). Treatment response was significantly influenced by approach (laparoscopic favored; p=0.001), surgery duration (<150 minutes better; p=0.017), mass pathology (adenoma favored; p=0.034), and capsular invasion (absence better; p=0.012). Conclusion: Adrenalectomy outcomes were significantly affected by surgical approach and tumor pathology, notably capsular invasion. Larger studies are needed to determine the predictive values of clinical and pathologic variables in adrenalectomy for adrenal tumors.
