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

Tropical forests host considerable biodiversity but face degradation from timber extraction ("logging"). We examined how logging intensity affected tree diversity, species composition, community wood density and availability of timber species in a lowland forest in north-central Vietnam. We measured and identified trees in 18 quarter-hectare plots that vary in historical logging intensity. Tree diversity showed no significant relationships with logging intensity. However, species composition differed, with each logging intensity class having distinct abundant tree species. Community wood density decreased significantly with logging intensity, being 9% lower in heavily than in lightly logged forests. Timber species were scarce overall, and individuals of harvestable size were most common in lightly logged forests. These results show that while tree diversity can persist after logging, heavy logging shifts community composition towards lighter-wood species and depletes valuable timber trees, reducing both carbon storage and timber potential. Reducing logging intensities is therefore critical for maintaining and increasing community wood density, carbon stocks and sustainable timber supplies in these forests in north-central Vietnam.
