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

In this study, we examined filarial infections in Japanese black bears around the Lake Towada area from 2020 to 2022. Microfilariae were observed in 81.6% of blood smears. Consistent with previous findings in Iwate Prefecture, polymerase chain reaction (PCR) analysis detected Dirofilaria ursi (89.7%) and Mansonella sp. (66.7%) in extracted blood DNA. The body size of D. ursi microfilariae matched previous reports, whereas Mansonella sp. microfilariae were smaller than those of D. ursi and other known species. Although we attempted to identify Mansonella sp. adult filariae using PCR, all recovered adults were D. ursi; no adult Mansonella sp. were detected. Further studies are needed to better identify and understand both the adult filariae and microfilariae of Mansonella sp. in Japanese black bears.
