Tracking bioturbation through time: The evolution of the marine sedimentary mixed and transition layers.
Article in Science advances, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Cited by 1 paper.
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.
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 physical, biogeochemical, and ecological properties of the modern seafloor are extensively shaped by the activities of burrowing and sediment-mixing animals, processes collectively known as bioturbation. Bioturbation is primarily recorded by homogenized sediments of the seafloor mixed layer and the underlying transition layer of discrete burrows. Although these two zones can be readily measured today, there has been limited understanding of how the mixed and transition layers evolved over the Phanerozoic since animals first began to extensively colonize the seafloor. Here, we provide a record for the depths of the sedimentary mixed and transition layers through the Phanerozoic. We find that although deepening of the sediment mixed layer spanned hundreds of millions of years, a deep transition layer was established as early as the Cambrian and did not further deepen until the Mesozoic-trajectories reflecting evolutionary radiations, changes in nutrient cycling, and alleviation of oxygen stress.
