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

backgroundTurtles have special anatomical features due to their shell and the enclosure of their internal organs. One of the important differences between the anatomy of this group of reptiles and others is the skeletal structure. The European pond turtle (Emys orbicularis) is a species within the Emylidae family, inhabiting regions spanning Europe, Africa and Asia.

objectiveThis study has been designed to assess the anatomical features of the appendicular skeletal system in this species and draw comparisons with other turtle species.

methodsComputed tomography (CT) Scan Machine and Micro CT Scan Machine were used for this study. Gross anatomical studies were performed on prepared bones using the method of using insects.

resultsThe carpal region consists of 10 bones (5 proximal and 5 distal), whereas the tarsal region features a fused Astragalus and four distal bones, both following a 2.3.3.3.2 phalangeal formula. Significant sexual dimorphism is limited to the pelvic girdle, where males exhibit a more prominent pubic ridge and an ossified symphysis compared to the predominantly cartilaginous structure in females.

conclusionsThe European pond turtle displays distinct anatomical characteristics compared to other turtle species, particularly aquatic ones. Notably, this turtle exhibits nails on all its manus digits, which are elongated and non-fin-like. In conclusion, the use of diagnostic imaging techniques, such as CT scans and micro-CT scans, in the study of turtle skeletons has proven to be highly beneficial. These techniques enable researchers to accurately determine the direction and position of bones, even in species with complex anatomical features like turtles.
