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 ocean, because of its ability to store heat and as the biggest mediator of water exchanges on Earth, modulates the climate from years to centuries. By combining Water Mass transformation and the Temporal-Residual-Mean frameworks, together with a direct estimation of turbulent diffusivity (computed through an artificial intelligence method), we determine temperature and salinity transformations along density surfaces. Because isopycnal transformations barely alter the density field, they remain hidden from the ocean dynamics. Here we unveil these hidden, isopycnal transformations from in situ observations at 1000-m depth. We shows that these isopycnal transformations are 5 times as large as their diapycnal counterpart and are occurring for  ~ 67% in the Southern Ocean. Our estimations stress the role of the spatially-varying and anisotropic characteristics of isopycnal diffusion, often not considered in ocean models. This has major consequences for our understanding of the role of the ocean in response to anthropogenic climate changes.
