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

This article analyses how and why individuals maintain or change their European solidarity over time using German panel data. I answer two questions: (1) Who maintains their level of European solidarity? (2) Do identity-based, value-based, or utilitarian approaches best explain change in European solidarity? I examine four dimensions of solidarity: territorial, fiscal, and welfare solidarity, and the support for European social citizenship. Despite COVID-19 and Russia's invasion of Ukraine, 44-57% of German respondents maintained stable solidarity. Stability varied little across sociodemographic groups. Those who identified more with Europe and on the economic and transnationalist left were less likely to reduce their solidarity. Transnational political orientation is the main driver of intra-individual change in European solidarity. When individuals come to identify more with Europe, they increase their solidarity, whereas national identification has inconsistent effects. Utilitarian factors, including exposure to regional crises, show little effect on individual solidarity. The findings add nuance to identity-based and utilitarian explanations of how individuals develop and maintain European solidarity.
