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

Ducks are the natural host and reservoir of influenza viruses. We are interested in their immune responses to these viruses, to understand host-pathogen interactions and to develop effective agricultural vaccines. We identified duck homologues of the chemokines CCL19 and CCL21 and cloned their cognate receptor, CCR7. Conservation of key features, and expression in lymphoid tissues suggests that these chemokines are the direct orthologues of their mammalian counterparts. Mammalian CCL19 and CCL21 are responsible for the homing of dendritic cells and naïve lymphocytes to secondary lymphoid tissues. The contribution of local tertiary lymphoid tissues may be important during influenza infection in ducks. Consistent with leukocyte recruitment, CCL19 and CCL21 transcripts are abundant in lung tissues at 1 day post-infection with highly pathogenic avian influenza A/Vietnam/1203/04 (H5N1) (VN1203). In contrast, expression in lung or intestine tissues infected with low pathogenic A/mallard/BC/500/05 (H5N2) (BC500) is not significant. Recruitment and aggregation of leukocytes is visible in the vicinity of major airways 3 days after infection with VN1203. Chemokine gene expression may serve as a useful marker to evaluate duck immune responses to natural infections and vaccine strains.
