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

backgroundClonal hematopoiesis (CH) is associated with adverse outcomes. We hypothesized that CH (JAK2V617F and CALR) is associated with cancer, vascular disease, and all-cause mortality, even at a variant allele frequency (VAF) <1%.

methodsWe screened 19,832 individuals from the Danish General Suburban Population Study for JAK2V617F and CALR mutations by digital-droplet PCR. We used Cox regression with hazard ratio (HR) and 95% confidence interval (95%CI), stratified by CH (JAK2V617F and CALR), VAF (<1% vs. ≥1%), mutation type (JAK2V617F or CALR), and JAK2V617F VAF.

resultsThe HR (95%CI) for any cancer was 1.71 (1.46-2.01) in CH, 1.28 (1.05-1.56) in VAF < 1%, 4.35 (3.34-5.66) in VAF ≥ 1%, and higher for JAK2V617F but not CALR. For hematological cancer, the HR (95%CI) was 8.41 (6.44-10.99) in CH, 3.53 (2.35-5.30) in VAF < 1%, and 40.01 (28.97-55.26) in VAF ≥ 1%, and also higher for JAK2V617F and CALR. For arterial diseases, the HR (95%CI) was 1.25 (1.03-1.52) in CH, 1.75 (1.18-2.59) in VAF ≥ 1%, and 1.28 (1.05-1.55) in JAK2V617F. The HR for venous disease was only higher in JAK2V617F VAF ≥ 1%. The HR (95%CI) for all-cause mortality was 1.45 (1.19-1.75) in CH, 1.36 (1.10-1.69) in VAF < 1%, 1.91 (1.26-2.88) in VAF ≥ 1%, and also higher for JAK2V617F and CALR. The population-attributable risk proportion (95%CI) for myeloproliferative neoplasms (MPNs) was 76.6% (66.8-86.4) in CH, 47.1% (29.6-64.6) in VAF < 1%, and 71.0% (59.4-82.6) in VAF ≥ 1%, with a nomogram generated.

conclusionsCH-defined by the JAK2V617F and CALR mutations-was associated with cancer, MPN, all-cause mortality-even with VAF < 1%-and vascular diseases at VAF ≥ 1%. These are novel findings, indicating that the JAK2V617F and CALR mutations confer an oncogenic potential with a VAF below the current CH of indeterminate potential definition.
