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

Sports participation gaps persist among certain demographic groups in many countries. Lower participation levels not only compromise the health of these groups but also undermine social cohesion. We conduct a large-scale field experiment to uncover the dynamics of discrimination against immigrants and ethnic minorities across multiple amateur sports. By emailing more than 8,900 sports clubs across seven popular sports in Germany, we find that individuals with native-sounding names are more likely to receive positive responses, with Syrian- and Turkish-sounding names facing the largest differences. The pattern persists across various sports, with some heterogeneity. Openly asking about club membership fees in the email has no influence. The results are robust to alternative models and specifications, including a data-driven causal random forest approach. We discuss implications for governing bodies, attitudes toward foreigners in German society, and future research in this field.
