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

Thylacocephala is one of the most puzzling groups of fossil marine euarthropods. They are known from the Silurian to the Cretaceous and are characterized by a univalve shield, hypertrophied compound eyes, three pairs of large, raptorial appendages and an 8 to 22 segmented posterior trunk. Despite this knowledge of their anatomy, numerous questions remain on their phylogenetic affinities. Usually considered as pancrustaceans, they have been tentatively placed within various pancrustacean ingroups such as thecostracans, malacostracans or remipeds. This uncertainty on their phylogenetic relationships is mostly due to a lack of knowledge on their body organization, especially on the number, nature and morphology of their cephalic, raptorial and posterior trunk appendages. We applied synchrotron X-ray microtomography to exceptionally preserved specimens of
