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

Peer defending is widely promoted as a strategy to reduce bullying, but few studies have investigated whether having more defenders decreases victimization over time from the victim's perspective. This social network study examined the longitudinal association between nominating more defenders and subsequent victimization among (early) adolescents and tested whether this relation is moderated by the popularity status of the defender and the victim. The sample included 1450 participants from 93 secondary school classes (grades 4-9) in Finland (52.51% female; M
