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

Hedgehogs (e.g., Erinaceus europaeus, E. roumanicus) are wild mammals that frequently are observed near residential areas. The aim of this study was to investigate ticks and fleas collected from European hedgehogs in Portugal and to evaluate the prevalence of Rickettsia in those ectoparasites. Ticks and fleas were identified by morphological and molecular methods, and molecular detection by PCR and genotypic characterization of Rickettsia spp. was performed targeting ompB, ompA and gltA gene fragments. In total, 1892 ticks and 213 fleas were collected from 33 rescued European hedgehogs captured in seven districts of the north and centre of Portugal. Two tick species were identified - Rhipicephalus sanguineus accounted for 91 % (n = 1719) of the total ticks collected and 9 % (n = 173) were Ixodes hexagonus. All fleas were identified as Archaeopsylla erinacei. Regarding pathogen detection, Rickettsia massiliae DNA was found in 22 of the 212 tested Rh. sanguineus. None of the 48 I. hexagonus tested showed to be positive for rickettsiae. Rickettsia asembonensis DNA was identified in 55 A. erinacei fleas tested (n = 117). These results show that European hedgehogs are exposed to R. massiliae transmitted by ticks and to R. asembonensis via fleas suggesting that these mammals might be involved in the natural transmission cycle of these Rickettsia species. This study is the first report of R. asembonensis in fleas in Portugal.
