Specific Features of Cerebral Venous Thrombosis Associated With Iron Deficiency Anemia.

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
backgroundAnemia has emerged as a risk factor for cerebral venous thrombosis (CVT) and has been associated with poorer outcomes. A specific association has been observed with microcytic anemia, most commonly caused by iron deficiency anemia (IDA). However, detailed data on the clinical, radiological, and therapeutic profile of CVT in patients with IDA remain limited.
methodsWe analyzed consecutive patients with CVT and moderate or severe IDA from the prospective Lariboisière Hospital cohort with CVT (1998-2023). Patients with other types of anemia were excluded. Clinical, neuroimaging, treatment, and outcome data were compared with those of patients with CVT without anemia.
resultsAmong 616 patients with CVT, 64 (10.4%) had moderate or severe IDA. Most were women (96.9%), with chronic gynecological bleeding (eg, fibroids, adenomyosis) as the predominant cause. All received anticoagulation. Additional treatments included iron supplementation, blood transfusion, gynecological surgery, and gonadotropin-releasing hormone analogs. Compared with patients without anemia (n=502), those with IDA more frequently presented with focal neurological deficits and parenchymal lesions (54.7% versus 35.3%,
conclusionsIDA is a prevalent comorbidity in CVT, affecting predominantly young women with benign, treatable causes of IDA. Although associated with more severe initial findings, long-term outcomes did not differ from those of patients without IDA. Appropriate recognition and specific management of IDA should be considered in patients with CVT.
