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

The knowledge gap hypothesis-the assumption that an increasing flow of news on a topic fosters a gap in knowledge between the more and the less educated-has been demonstrated in numerous studies throughout the past 60 years. Knowledge gaps are attributed to individual differences in media selection and information processing capacities. However, it has been difficult to investigate the relative influence of selection and processing with conventional research methods. We used an innovative combination of individual-level digital trace and survey data collected in Switzerland (
