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

objectiveBorreliosis is a tickborne disease caused by several species of Borrelia spirochete. In Japan, autochthonous cases are increasing in Hokkaido, and in the central Honshu, where Niigata is located. This study aimed to reckon the presence of Borrelia spp. in ticks and its epidemiological significance in Niigata prefecture.

resultsFrom 41 sites of Niigata, 1,939 DNA samples from ticks were tested for the presence of Borrelia spp. by PCR. The spirochete was detected in 55 samples, resulting in a prevalence of 2.83% (55/1,939) overall. The DNA sequencing analysis revealed 3 species of Borrelia in Niigata prefecture, B. japonica 76.4% (42/55), B. miyamotoi 3.6% (2/55) and an unidentified Borrelia sp. 20% (11/55). Borrelia japonica was detected from adults of Ixodes ovatus, predominantly in females. Higher prevalence of B. japonica was found in Joetsu area, border with Nagano and Toyama prefectures. B. miyamotoi was detected in Chuetsu region, the central area of Niigata in adult females of I. ovatus. One type of Borrelia, identified to genus level, was detected in larvae, nymph and adult stages of Haemaphysalis spp. ticks mainly in Kaetsu, the northern region of the prefecture.
