ASSESSMENT AND COMPARISON OF HORMONAL IMMUNOEXPRESSION AND THE CLINICAL PICTURE IN PATIENTS WITH PITUITARY ADENOMAS.
Article in Acta endocrinologica (Bucharest, Romania : 2005). The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
introductionSymptoms related to hypersecretion of hormones in patients with pituitary adenomas do not always correlate with immunohistochemical staining results.
objectiveTo evaluate the relationship between the pituitary adenomas hormone immunoexpressions and endocrine presentations. PATIENTS AND
methodsThe clinical status and immunoexpression of 72 patients who underwent transsphenoidal surgery for pituitary adenomas were analyzed.
resultsMacroadenomas were diagnosed in 51 cases (70.84%), while microadenomas were found in 21 cases (29.16%). The 72 adenoma specimens were divided into 22 monohormonal, 21 plurihormonal, 21 immunonegative and 8 unreliable specimens. The positive immunohistochemical staining results occurred as follows: prolactin and growth hormone 25% each, adrenocorticotropic hormone 13.89%, thyroid-stimulating hormone 5.56%, leuteinizing hormone and follicle-stimulating hormone 12.5%, glycoprotein hormone alpha-subunit 22.22%. Statistically significant relationships between the immunohistochemical presentation and the preoperative diagnosis were found for prolactin and hyperprolactinemia, growth hormone and acromegaly and adrenocorticotropic hormone and Cushing's syndrome.
conclusionsThe lack of full concordance between the clinical presentations and immunohistochemical staining was mainly a result of the presence of nonfunctioning adenomas, plurihormonal adenomas and unreliable specimens. The morphometric method introduced in this study, utilizing the immunoexpression index, provided a very precise evaluation of pituitary adenomas pathology.
