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

A new ascaridoid nematode, Hysterothylacium malleocaudatum sp. n., was described using both light and scanning electron microscopy, based on specimens collected from the greater amberjack Seriola dumerili (Risso) (Carangiformes: Carangidae) in the Persian Gulf off Iraq. The new species can be distinguished from the congeners by the combination of the following features, the presence of remarkable lateral alae starting from base of ventro-lateral lips, the short intestinal caecum and long ventricular appendix (intestinal caecum representing 21.1-40.5% of oesophageal length, ratio of intestinal caecum to ventricular appendix 1: 1.42-3.77), the relatively long oesophagus (oesophageal length representing 9.83-14.3 % body length), the number and arrangement of the caudal papillae (31-37 pairs precloacal, 1-2 pairs paracloacal and 6 pairs postcloacal), and the presence of inflated hammer-shaped tail tip in both sexes. The new species represents the fourth Hysterothylacium species reported in marine fishes from Persian Gulf, off Iraq.
