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

Anaplasma phagocytophilum, the causative agent of tick-borne human granulocytic anaplasmosis (HGA), is an intracellular bacterium which survives and multiplies inside polymorphonuclear neutrophil granulocytes (PMN). Increased bacterial burden in gamma interferon (IFN-gamma)-deficient mice suggested a major role of IFN-gamma in the control of A. phagocytophilum. Here we investigated whether infection of human PMN with A. phagocytophilum impairs IFN-gamma signaling thus facilitating intracellular survival of the bacterium. The secretion of the IFN-gamma-inducible chemokines IP-10/CXCL10 and MIG/CXCL9 was markedly inhibited in infected neutrophils. Molecular analyses revealed that, compared to uninfected PMN, A. phagocytophilum decreased the expression of the IFN-gamma receptor alpha-chain CD119, diminished the IFN-gamma-induced phosphorylation of STAT1, and enhanced the expression of SOCS1 and SOCS3 in PMN. Since IFN-gamma activates various antibacterial effector mechanisms of PMN, the impaired IFN-gamma signaling in infected cells likely contributes to the survival of A. phagocytophilum inside PMN and to HGA disease development.
