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

Leucocytozoon spp. are common avian haemosporidian parasites that can cause clinical symptoms with lethal cases in poultry worldwide. However, leucocytozoonosis has not been reported in domestic ducks (Anas platyrhynchos domesticus) in Japan. Two adult domestic ducks maintained in a zoological garden in Japan became lethargic, exhibited labored breathing, and died in July 2024. These ducks had hemorrhages in the visceral organs with splenomegaly and hepatomegaly. Megaloschizonts of haemosporidia were histologically observed in the spleen and other organs. Partial sequences of Leucocytozoon mitochondrial cytochrome b gene DNA were determined and classified as lineages known to infect wild waterfowl (Anseriformes). To the best of our knowledge, this is the first known fatal case of leucocytozoonosis in domestic ducks in Japan.
