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

Long-term culture of the human lung adenocarcinoma cell line A549 promotes the differentiation of these cells toward an alveolar type II cell phenotype. Here, we evaluated the susceptibility of long-term cultured A549 cells to human influenza viruses. A549 cells were cultured continuously for 25 days (D25-A549) or 1 day (D1-A549) in Ham's F12K medium. Six human influenza A viruses grew much faster in D25-A549 cells than in D1-A549 cells; however, two influenza B viruses replicated poorly in both cell types. Two avian influenza viruses replicated efficiently in both cell types, with similar titres. Expression levels of human virus receptors were higher in D25-A549 cells than in D1-A549 cells. D25-A549 cells thus more efficiently support the replication of human influenza A viruses compared with D1-A549 cells. Our data suggest that long-term cultured A549 cells will be useful for influenza A virus research.
