Curtailing the Path From Epistaxis to Genetics: The Diagnostic Value of Detailed Medical History in Hereditary Macrothrombocytopenia.
Article in Cureus, 2026. 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
Hereditary macrothrombocytopenias represent a heterogeneous group of inherited platelet disorders that may present with variable, often mild, bleeding symptoms and are frequently misdiagnosed as acquired thrombocytopenias. This report presents a four-year-old boy with recurrent severe epistaxis and a family history of increased bleeding tendencies accompanied by low platelet counts. The patient had mild thrombocytopenia, large platelets, and a slightly prolonged platelet function analysis, while standard coagulation studies and thromboelastography were within normal limits. Next-generation sequencing identified a heterozygous variant in the alpha-actinin-1 (ACTN1) gene, confirming the diagnosis of ACTN1-related thrombocytopenia. Management consisted of supportive care and observation. This case underscores the significance of genetic testing in the diagnostic evaluation of suspected hereditary thrombocytopenias to facilitate accurate diagnosis, prevent unnecessary interventions, and enable appropriate genetic counseling for affected families.
