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

Urban environments expose resident organisms to intense, multifaceted selective pressures. Studies employing intraspecific responses of functional traits have proven particularly valuable for understanding vegetation ecological strategy under urbanization. Here, we compiled a dataset of ten leaf functional traits of 1051 observations of 322 species from 104 cities to assess the impacts of urbanization. Urban-related moderators (climatic region, air quality and build up area), phylogenetic group, leaf habits and study design were considered. Results showed that leaf thickness (LT) and leaf dry matter content (LDMC) significantly increased, while the photosynthetic rate under saturating light (
