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

Habitat fragmentation and degradation are major problems in tropical forests, leading to a decline in biodiversity. However, it is often unclear which aspects of habitat change are responsible for the decline of specific species. Physiological studies can help identify potential stressors and elucidate causal relationships between habitat change and species decline. In this study, we measured the heterophil-to-lymphocyte (H:L) ratio as an indicator of long-term physiological stress and ecological pressures, such as pathogen exposure or risk of injury, in the tropical understorey insectivore Cabanis's Greenbul (Placid) ( Supplementary Information: The online version contains supplementary material available at 10.1007/s10336-025-02321-0.
