Endoscopic therapy and curative effect in pituitary adenoma patients complicated by acromegalic cardiomyopathy.
Article in Neurosurgical review, 2018. 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
The study aimed to retrospectively analyze the clinical characteristics of patients with pituitary adenomas complicated by acromegalic cardiomyopathy and to evaluate the effect of endoscopic surgery. Eighty-six pituitary adenoma patients complicated by acromegalic cardiomyopathy who were treated with endoscopic surgery in the First Affiliated Hospital of Soochow University from January 2010 to December 2016 were enrolled. We noted patient clinical characteristics and explored the relationships with surgical treatment. Before and after surgery, all patients underwent an examination of pituitary endocrinology, brain magnetic resonance (MR), and echocardiography. The serum levels of growth hormone (GH), left ventricular end-diastolic diameter (LVIDd), interventricular septal thickness (IVST), left ventricular posterior wall thickness (LVPWT), left ventricular ejection fraction (EF), and mitral valve (E/A ratio) were examined with non-invasive methods, and the results were compared. Of the 86 patients, there were 23 with microadenomas, 27 with large adenomas, and 36 with giant adenomas. There were 28 patients with invasive adenomas and 58 with non-invasive adenomas. The pre-operative mean GH level was 71.23 ± 3.29 μg/L, which was positively correlated with tumor volume (r = 0.751, P < 0.01). Via trans-sphenoidal endoscopic pituitary adenoma resection, 51 patients underwent total tumor resections, 25 underwent subtotal resections, 8 underwent major part resections, and 2 underwent partial resections. After surgery, the GH mean level was 3.81 ± 1.03 μg/L, which was significantly different (t = 3.72, P < 0.01) from the pre-operative level. Cardiac function indices, including LVIDd, IVST, LVPWT, E/A, and EF, were significantly improved. The long-term curative rate was 39.17% and the remission rate was 77.29%. For pituitary adenoma patients complicated by acromegalic cardiomyopathy, endoscopic surgery resulted in a good curative effect and the growth hormone levels were maintained, which can significantly improve cardiac structure and function.
