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

Emicizumab shortens activated partial thromboplastin time (aPTT) greater than Factor (F)VIII. Clot waveform analysis triggered by ellagic acid and tissue factor trigger (Elg/TF) provided a useful means of assessing emicizumab activity. Thrombin generation assays (TGA) using this trigger reagent might also overcome the difficulties associated with aPTT by emicizumab. To compare TGA triggered by Elg/TF and other reagents (FXIa, TF) for evaluating emicizumab activity. Emicizumab, FVIII, or FVIII-bypassing agents (BPAs) were incubated with FVIII-deficient plasmas prior to TGA initiated by Elg/TF (0.2 μM/0.5 pM), FXIa (5.21 pM), or TF (PPP-Reagent LOW
