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

The Tsugaru Strait is a critical conduit linking the Sea of Japan and the Pacific Ocean and is characterized by a vigorous eastward current. Here, we use high-resolution surface current data acquired from a high-frequency radar system in conjunction with direct turbulence measurements to show that the large increase in chlorophyll-a within a hundred kilometre-scale anticyclonic gyre is driven by the intensification of turbulence, extraordinarily high diffusive nitrate fluxes and divergent flow fields limited to a very narrow area. Enhanced mixing and nutrient fluxes are caused by the presence of a distinct topographic feature-an underwater seamount-within the path of the Tsugaru Strait water flow. Our long-term datasets reveal a positive correlation between recurring submesoscale divergence related to the topographic features and the downstream distribution of chlorophyll-a. This finding reinforces the significant role of the underwater seamount in enhancing the productivity of the downstream anticyclonic gyre. The results of this study emphasize the importance of re-evaluating nutrient supply processes with respect to submesoscale interactions with underwater seamounts for large-scale enhanced biological productivity.
