Diagnosis of platelet dysfunction in children: clinical predictors and test methods.
Article in Blood vessels, thrombosis & hemostasis, 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
Evaluation for platelet function disorders (PFD) in children is complicated by their limited exposure to hemostatic challenges, large volumes needed for light transmission aggregometry (LTA) testing, and limited data on the performance characteristics of whole-blood methods such as whole-blood impedance lumiaggregometry (WBILA). The objective of this study was to determine the clinical variables associated with the diagnosis of a PFD. A single-center, retrospective, cohort study of children evaluated for PFD was conducted. Medical charts were abstracted for demographics, medications, testing indications, bleeding sites and severity, and laboratory results. Univariate odds ratios (OR) and multivariable modeling were conducted for association of clinical variables with PFD diagnosis in children tested by LTA or WBILA. Of 667 patients, 20.5% were diagnosed with a PFD. The PFD cohort was more likely male (OR, 1.54;
