Pheochromocytoma: Clinical Experience From a Single Tertiary Care Center in India.
Article in Cureus, 2023. 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
introductionPheochromocytoma is a catecholamine-secreting tumor arising from adrenomedullary chromaffin cells that has a varied clinical presentation. Identification of this tumor, which has episodic symptoms, is a diagnostic challenge for clinicians. Diagnosis at an appropriate time is important because it is associated with significant morbidity and mortality. This study aims to mitigate the limited availability of data in our geographical area. AIMS AND
objectivesTo assess the clinical, biochemical, and radiological features and outcomes of patients diagnosed with pheochromocytoma at our center. MATERIALS AND
methodsThis is a retrospective study. Patients diagnosed with pheochromocytoma during 2015-2023 were included in the study. Clinical, biochemical, and radiological data were collected at presentation, post-surgery, discharge, and until the last follow-up; data were retrieved from hospital records. Statistical analysis was done using IBM Corp. Released 2011. IBM SPSS Statistics for Windows, Version 20.0. Armonk, NY: IBM Corp.
resultsThis study included 19 patients, of whom 10 (52.6%) were female. The most common clinical presentation was a hypertensive crisis in patients with pre-existing hypertension (63.1%), followed by headache (47.3%). The classical triad of headache, palpitation, and sweating was seen in only three patients (15.7%). The mean tumor size was 5.01±2.06 cm, with a range of 2.5 to 12 cm. All patients underwent adrenalectomy; six patients (31.5%) had perioperative complications, with post-operative hypotension being the most common at 21% (n = 4), followed by an acute coronary event during alpha blockade in one patient (0.05%) and an intra-operative hypertensive crisis in one patient (5%). A biochemical remission rate post-surgery was achieved in 17 (89.47%) patients.
conclusionsHypertensive crisis in patients with pre-existing hypertension was the predominant presenting feature in most of our patients. Female predominance was noted (52.3%) compared to males. Perioperative complications were observed in 31.5% of patients, with post-operative hypotension being the most common complication.
