Quantitative analysis of catecholamines and their metabolites in 491 patients with adrenal tumors: a retrospective single-center cohort study.

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
backgroundAdrenal tumors, including benign cortical adenoma (BCA) and pheochromocytoma (PCC) or paraganglioma (PGL), have been more frequently detected during imaging examinations in recent years. However, the associated clinical or laboratory characteristics, especially on the Chinese population, still need to be investigated.
methodsWe conducted a retrospective analysis of 491 patients pathologically diagnosed with adrenal tumors, from Jan 19, 2018 to Dec 17, 2019, at a tertiary referral hospital in Wuhan of China. Our findings including 247 (50.3%) BCA cases, and 92 (18.7) PCC/PGL cases and other cases. Both the clinical and laboratory parameters were reviewed and analyzed.
resultsCompared with other adrenal tumors, PCC/PGL showed larger tumor diameters and more frequently located on the right side, and were with higher levels of urinary catecholoamines and plasma metanephrines, especially for the 24 h urinary vanilmandelic acid (VMA) and plasma normetanephrine (NMN). The optimal diagnostic thresholds were 29.40 ug/24 h for VMA (sensitivity, 85%; specificity, 91%) and 0.63 nmol/L for NMN (sensitivity, 91%; specificity, 92%). The 24 h urinary VMA and plasma NMN also shared abilities to differentiate between different tumor laterality and different tumor size in PCC/PGL cases. In addition, compared with the other benign tumors, BCA were smaller in diameters (20 vs 35 mm, p < 0.001), and seemed to be lower in levels of plasma epinephrine, dopamine and serum ACTH.
conclusion24 h Urinary catecholoamines and plasma metanephrines, especially for the 24 h urinary VMA and plasma MNM, showed higher diagnostic efficacies for PCC/PGL, and were tightly associated with the tumor laterality and tumor size.
