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

Intertidal habitat heterogeneity can shape macrobenthic communities, but its links to assembly processes and network stability remain uncertain. Macrobenthos were surveyed at 22 sites across muddy sediment (MA), oyster farming (OF), eastern rocky reef (EA), and southern rocky reef (SA) habitats around Nan'ao Island. Habitat type explained 25.5% of compositional variation, whereas observed richness and evenness showed no consistent among habitat differences. Mean between-habitat Bray-Curtis dissimilarity (0.730) and turnover (0.623) exceeded their within-habitat values (0.634 and 0.555), indicating that species replacement, rather than nested species loss, dominated community differentiation. Functional richness differed among habitats, whereas most other functional indices remained comparatively stable. Neutral-model fits were stronger in EA and SA (R
