Hemorrhagic PitNets Are Associated with Previous Vascular Events and Result in Worse Endocrine Outcome.
Article in Cancers, 2024. 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
backgroundPituitary apoplexy is a potentially life-threatening condition that most often results from hemorrhage into a preexisting pituitary neuroendocrine tumor (PitNet) presenting with acute headache, visual impairment and endocrine dysfunction. Here, we aimed to identify factors associated with hemorrhage and present the pituitary hormonal status before and after transnasal-transsphenoidal tumor removal in a comparative study design.
methodsA series of 100 patients with PitNet were analyzed. We compared demographic data (age, sex, BMI), comorbidities, tumor volume and neuropathological findings between patients who presented with hemorrhagic PitNet (H-PitNet) and those with non-hemorrhagic PitNet (NH-PitNet). Furthermore, we compared the axis-specific hormonal status between both groups at admission and after microsurgical tumor removal and analyzed the overall endocrine outcome in both groups.
resultsA total of 22 patients presented with hemorrhagic PitNet. There were no differences in age, sex, BMI, tumor volume, smoking status or diabetes status between patients with H-PitNet and those with NH-PitNet. H-PitNet was strongly associated with necrotic areas (
conclusionsH-PitNet is associated with previous vascular event (ischemia or hemorrhage) and the presence of arterial hypertension and results in worse endocrine outcome. Early surgery should be considered in patients with PitNet and arterial hypertension.
