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

Paroxysmal nocturnal hemoglobinuria (PNH) is a rare hematologic disease that presents with protean manifestations. Clinical and laboratory investigation over the past 25 years has uncovered most of the basic science underpinnings of PNH and has led to the development of a highly effective targeted therapy. PNH originates from a multipotent hematopoietic stem cell (HSC) that acquires a somatic mutation in a gene called phosphatidylinositol glycan anchor biosynthesis, class A (PIG-A). The PIG-A gene is required for the first step in glycosylphosphatidylinositol (GPI) anchor biosynthesis. Failure to synthesize GPI anchors leads to an absence of all proteins that utilize GPI to attach to the plasma membrane. Two GPI-anchor proteins, CD55 and CD59, are complement regulatory proteins; their absence on the surface of PNH cells leads to complement-mediated hemolysis. The release of free hemoglobin leads to scavenging of nitric oxide and contributes to many clinical manifestations, including esophageal spasm, fatigue, and possibly thrombosis. Aerolysin is a pore-forming toxin that binds GPI-anchored proteins and kills normal cells, but not PNH cells. A fluorescinated aerolysin variant (FLAER) binds GPI-anchor and serves as a novel reagent diagnosing PNH. Eculizumab, a humanized monoclonal antibody against C5, is the first effective drug therapy for PNH.
