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

Background: Predictors for the successful eradication of neutralizing anti-FVIII alloantibodies (inhibitors) in hemophilia A patients receiving immune tolerance induction (ITI) therapy remain limited. Maternal microchimerism (MMc) showed potential to protect hemophilia A patients from inhibitor development. Objectives: To investigated the role of MMc in ITI therapy. Patients/Methods: This observational study enrolled 121 pediatric with hemophilia A and inhibitors. MMc was determined using droplet digital PCR. Low-dose ITI (FVIII ~50IU/kg every other day) was administered, with adjunctive rituximab given to patients with higher risk clinical features. Results: Of the 101 patients evaluable for MMc, 88 completed ITI, 18 were MMc positive (MMc+) and 70 were MMc negative (MMc-). Success was achieved in 75 (85.2%) patients, including 16 of 18 MMc+ patients (88.9%) and 59 of 70 MMc- patients (84.3%). Compared with MMc- patients, MMc+ patients had a lower peak inhibitor during ITI (median, 5.3 vs. 37.8 BU/ml, Conclusion: MMc was associated with more rapid ITI success in children with hemophilia A and inhibitors receiving low-dose ITI regimen, suggesting the potential role of MMc in facilitating the eradication of FVIII inhibitors.
