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.
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 AND
aimRecently, the MIRRA trial demonstrated the efficacy and safety of mepolizumab in refractory or relapsing eosinophilic granulomatosis with polyangiitis (EGPA) and the usefulness of this drug as a steroid-sparing agent. However, until now, only a few evidence is available about its effectiveness and safety in clinical practice. In this paper, we report our experience in the treatment of EGPA patients with mepolizumab in a real-world setting and review the current literature on this topic.
methodsWe retrospectively enrolled 14 patients that underwent mepolizumab therapy for EGPA at any dose and with a follow-up of at least 3 months. For each patient, demographic and clinical manifestations of the disease, laboratory parameters, BVAS, asthma exacerbations, and therapeutic management were recorded at the beginning and at the end of mepolizumab therapy.
resultsAfter a median follow-up of 16 months (3-60), all EGPA patients were in remission for both vasculitis and asthma manifestations. Mepolizumab was associated with a reduction in corticosteroids daily dose, with a significant number of patients able to discontinue corticosteroids (8/14 patients). No patients withdrew mepolizumab and no severe adverse events were recorded. Conclusion: Our data support the long-term effectiveness of mepolizumab and, in particular, they are suggestive for a good safety profile of this drug among patients with EGPA. In the nearest future, the possibility to obtain a sustained remission in EGPA without the use of steroids should be investigated in larger controlled studies.
