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

Paracamallanus cyathopharynx (Baylis, 1923) specimens were collected from the rectum of the African sharptooth catfish, Clarias gariepinus in Lake Heritage, Crocodile River in the Limpopo River system and in the Vaal River below the Vaal Dam. Attached and unattached parasites were studied with light and scanning electron microscopy along with infected and uninfected host tissue. The cuticle-lined buccal capsule and the muscular oesophagus attached to the epithelial lining and the cuticular ridges on the dorsal and ventral surface of the cavity provided traction that improved the grip. Sucking exerted by the oesophagus lifted and stripped the epithelium at the site of attachment, and a bolus of host tissue was ingested. The buccal capsule penetrated to the level of the lamina propria. The number of host mucus-secreting goblet cells increased significantly at the site of infection, and the proliferation of these cells were also significantly higher.
