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

backgroundEssential thrombocythemia (ET) is one of the "classic" Philadelphia chromosome negative (Ph-) myeloproliferative neoplasms characterized by sustained thrombocytosis, increased megakaryopoiesis and high risk of vascular complications. ET is very rare in childhood. The annual incidence is approximately 1 per 10,000,000 in children less than 14 years, and about 60 times lower than adults. The genetic landscape and clonal features in childhood ET has not been well defined. There is no evidence-based guidance on the diagnosis of childhood ET.

methodsMedical records of 28 pediatric patients (age ≤ 14 years at diagnosis) with ET were reviewed and evaluated to characterize the different mutation profiles and to evaluate the treatment modalities used and the potential long-term outcome.

resultsMore than half of the patients were found to have positive history of parental consanguinity (57.1%) whereas positive family history was documented for more than a quarter of our patients (28.6%). Janus kinase 2 gene (

conclusionsThe incidence of ET in children is extremely low in Saudi Arabia. Most of the children with ET were asymptomatic, and thrombocytosis was often discovered incidentally.
