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

purposeThe role of the Bruton tyrosine kinase (Btk) protein in neutrophil function has been evaluated using neutrophils from healthy volunteers after incubation with a Btk inhibitor, leflunomide metabolite analog (LFM-A13), suggesting an important role for Btk in neutrophil function. We sought to determine the role of Btk protein on neutrophil superoxide generation and chemotaxis stimulated by N-formyl-methionine-leucine-phenylalanine (fMLP).

methodsChemotaxis was assayed on agarose gel and superoxide generation by cytochrome C reduction. The affects of LFM-A13 on chemotaxis and superoxide generation in unstimulated and fMLP stimulated neutrophils were studied in Btk deficient neutrophils from XLA patients compared with matched controls analyzed simultaneously.

resultsChemotaxis and stimulated superoxide production were similar in the normal and Btk deficient neutrophils and were similarly inhibited by LFM-A13. In one patient, LFMA13 had no effect on superoxide generation in Btk deficient neutrophils up to a concentration of 25 microM, while inhibited superoxide production by control neutrophils.

conclusionsOur results suggest that Btk does not have a specific role in neutrophil fMLP-stimulated superoxide generation and chemotaxis since these activities were similarly inhibited by LFM-A13 in Btk deficient and normal neutrophils. The lack of superoxide generation following Btk inhibition by LFM-A13 in Btk deficient neutrophils from one patient may suggest some heterogeneity in the role of Btk in fMLP induced neutrophil superoxide generation.
