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

Worldwide reef ecosystem degradation is inspiring efforts to enhance in-situ coral larvae settlement onto degraded or artificial reefs. Here we simultaneously test three approaches for enhancing settlement over two weeks in Kāne'ohe Bay, O'ahu, Hawai'i. Nineteen artificial structures, mimicking natural reef mesoscale roughness, were deployed along two transect lines at distances between 1 and 42 m from an "acoustic enrichment" underwater speaker broadcasting healthy reef sound. Twelve additional cinder blocks supporting micro-habitat structures designed to attenuate flow were also deployed at various distances. Some micro-habitats were coated with a living bacteria reef ink (Brink) to further induce larval settlement. Statistical regressions identify Brink presence, structure type, and speaker distance to 20 m as significant factors in predicting coral larval settlement density, but conclusions about acoustic enrichment efficacy are tentative. The cumulative effects of acoustic enrichment, living microbial materials, and custom-designed habitats on enhancing in-situ larval settlement justify further scaled-up reef restoration trials.
