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

The fourth larval stage (L4) of Coronocyclus labratus (Looss, 1900) Hartwich, 1986, one of the common species of the Cyathostominae found in equids, is identified and described. The larvae found were identified as C. labratus by finding moulting forms possessing characters of both larval and adult stages. The larvae are similar to those of Cylicocyclus leptostomum (Kotlán, 1920) Foster, 1936, Cyathostomum catinatum Looss, 1900 and Cylicostephanus goldi (Boulenger, 1917) Lichtenfels, 1975. The buccal capsule (BC) wall of the L4 of Cylicocyclus leptostomum is thinner than that of Coronocyclus labratus, and the ring of the oesophageal funnel is comparatively less well developed. In C. labratus the dorsal tooth protrudes only slightly into the buccal cavity, and this larva possesses a characteristically elongate, pyriform oesophagus. In Cyathostomum catinatum, the BC walls are thicker than in Coronocyclus labratus, and the dorsal tooth is more bluntly pointed. Sublateral teeth, if present, are bluntly pointed in the former species, but usually absent or indistinct in C. labratus. Larvae of Cylicostephanus goldi differ from those of Coronocyclus labratus in the larger size of the BC.
