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

Tunas are high-performance pelagic fishes of considerable economic importance and have a suite of biological adaptations for high-speed locomotion. In contrast to our understanding of tuna body and muscle function, mechanosensory systems of tuna are poorly understood. Here we present the discovery of a remarkable sensory lateral line canal within the bilateral tuna keels with tubules that extend to the upper and lower keel surfaces. Neuromast mechanoreceptor organs are found periodically along the canal lumen, enclosed within tubular ossifications surrounding the canal that we interpret as modified lateral line scales. In addition, a series of segmental, elongated skeletal elements of unknown homology support the posterior end of the keel. These observations suggest that the bilateral tuna keels act as flow sensing structures, perhaps providing information on tail beat frequency, amplitude, force, and water flow dynamics over the caudal region of the tuna body axis during locomotion.
