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

Systemic mastocytosis (SM) is a myeloproliferative disorder marked by accumulation of clonal mast cells (MC) and a 100-fold increased risk of potentially life-threatening anaphylaxis not fully preventable with antimediator treatments. Omalizumab can be effective but is off-label and variably available. The effect of cytoreductive treatments such as interferon-alpha, cladribine, and tyrosine kinase inhibitors (TKIs) on anaphylaxis in SM remains unclear. We present a patient with indolent systemic mastocytosis and recurrent life-threatening anaphylaxis despite maximum antimediator treatment and omalizumab who experienced immediate resolution of ongoing anaphylaxis upon initiation of midostaurin treatment. No anaphylaxis recurrence was observed during 25 months of follow-up on midostaurin. A literature review on cytoreduction and anaphylaxis retrieved 18 studies. Despite the limited quality of evidence, a clear trend towards reduction of anaphylaxis-like symptoms was seen across all agents and SM subtypes with resolution and/or improvement noted in 95% of cases with a prior history of anaphylaxis. Immediate resolution of ongoing anaphylaxis observed in our case and the literature suggest cytoreduction can be used for treatment of refractory anaphylaxis and prevention of recurrent anaphylaxis in SM. Further exploration of cytoreduction for these indications is warranted.
