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

To improve our knowledge on the epidemiological, clinical and pathobiological profile of clonal megakaryocyte dysplasia with normal blood values (CMD-NBV), a BCR::ABL-negative myeloproliferative neoplasms clinical variant, we here report a series of 30 consecutive subjects with CMD-NBV. Sixteen subjects were men and the median age was 48 years (interquartile range [IQR], 39-53 years). A situation-driven diagnosis (70% of cases had the diagnosis triggered by an incidental or symptomatic venous or arterial thrombosis), high incidence of thrombotic events (6.5 events x 100 subject-years), and indolent disease (the 10-year CMD-NBV-specific survival was 100%) were common. Nineteen subjects had a high body mass index at diagnosis and 14 had ≥1 Charlson co-morbidities. In 21 the driver variant was JAK2V617F with a median variant allele frequency at diagnosis of 8.9% (IQR, 5.4-18.4%). Six of 24 (25%) subjects with data on next-generation sequencing for myeloid neoplasm-related genes had ≥1 pathogenic somatic variant in ASXL1, TET2, DNMT3A or SRSF2, a frequency in the lower range of values of chronic myeloproliferative neoplasms. Twelve putative germline, non-pathogenic, missense variants in ASXL1, TET2, DNMT3A, RUNX1, CUX1, ABL1, NF1, KIT and CSF3R or 5' UTR in NF1 and 3' UTR in ASXL1 were detected in ten of 24 (42%) subjects. These data further support identification of CMD-NBV as a distinct entity.
