Increased Prevalence of Thromboembolic Events in Patients with Congenital Dyserythropoietic Anemia Type I.

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
<p>Introduction: Congenital dyserythropoietic anemia type I (CDA-I) is a rare disorder of erythropoiesis. All CDA-I patients are expected to have iron overload and chronic hemolysis. Patients with severe anemia may undergo splenectomy. Hemochromatosis, chronic hemolysis, and splenectomy are all found to increase risk for thromboembolism in thalassemic patients. As CDA-I patients have similar findings, we sought to evaluate prevalence of thromboembolic events (TEEs) in these patients.
methodsA retrospective case-control study was conducted, including 110 CDA-I patients (study group) and 326 age- and sex-matched iron deficiency anemia patients of the same ethnicity (control group). Patients were risk-stratified using Risk Assessment Models for thromboembolism.
resultsWe identified 3 cases (2.7%) with TEEs in the CDA group and 1 case (0.3%) in the control group. All patients were females. VTE risk scores were low to moderate for CDA patients and higher for IDA patient. When compared to control group, CDA-I patients were nine times more likely to develop TEE (OR 9.11, 95% CI = 1.15-185.27, p = 0.057). All 3 CDA patients had a history of remarkable hemolysis and iron overload. Two underwent splenectomy.
conclusionThese findings show that CDA patients appear to be at increased risk for TEEs. </p>.
