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

To investigate whether ticks of the genus Ixodes are infected by Borrelia burgdorferi complex, 490 unfed Ixodes ricinus ticks were collected by flagging in three different areas of Tunisia in 1998. DNAs extracted from 81 adults, 60 nymphs and 38 larvae were analysed after genic amplification of the non-coding spacer between the two copies of the rrl-rrf genes of B. burgdorferi sl. The prevalence of B. burgdorferi sl. in adults, nymphs and larvae was found to be 34, 33.3 and 2.6%, respectively. All DNAs (n = 61) but one were identified as belonging to different genotypes of B. lusitaniae by analysis of the restriction fragment length polymorphism of amplification products. In addition, 290 adults, 14 nymphs and 7 larvae were used to inoculate BSK-H medium to isolate spirochetes. Fifteen strains were isolated from adult ticks in the humid areas of Tunisia, whereas only one was obtained from larvae. Isolates were identified as B. lusitaniae (15/16) and B. garinii (1/16). These results provide new evidence for the existence of Lyme borreliosis in North Africa.
