1 · What the graph read from it

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.

2 · The registry

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

Background: Myeloproliferative neoplasms (MPNs) represent a group of blood disorders characterized by myeloid cell proliferation and an associated increased risk of thrombosis and bleeding. Platelet count may have a direct link to these complications. Objectives: To share our MPN clinic's experience with hemostatic testing and bleeding outcomes in patients with platelets ≥ 800 × 10 Methods: This was a single-center retrospective study from May 2022 to September 2024. Clinical characteristics, treatments, and bleeding events of patients with MPN or chronic myeloid leukemia were recorded. Laboratory assessments included full blood count, renal function, coagulation profiles, platelet function test, and von Willebrand factor (VWF) assays. Results: A total of 39 patients were included, majority of whom received aspirin for thrombosis prevention (76%). The study found that bleeding complications occurred in 33% of patients, with mucocutaneous bleeding being the most common. There was a trend toward bleeding in patients on aspirin ( Conclusion: The study illustrates the limitations of relying solely on platelet counts to estimate bleeding risk in MPN patients. Assessment of VWF activity and careful selection of antithrombotic therapy were highlighted as important considerations.
