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

A survey to determine the prevalence of tick-borne diseases (TBDs) and ticks infesting cattle was conducted in the communal areas of the north-eastern region of the Eastern Cape Province (ECP) between January 2019 and October 2019. Tick counts, packed cell volume (PCV), body condition scores (BCS), and serological test for TBDs were seasonally conducted in communally grazed cattle (n = 240) in Joe Gqabi district in two local municipalities (Elundini and Senqu). A standard indirect fluorescent antibody test (IFAT) was used to determine antibodies to Babesia bigemina, Babesia bovis, and Ehrlichia ruminantium and indirect enzyme-linked immunosorbent assay (ELISA) was employed for antibodies to Anaplasma marginale detection. The highest tick loads were observed on cattle during the hot-wet and post-rainy seasons and lowest during the cool-dry season. The E. ruminantium prevalence in Elundini was 16% and 14% in post-rainy and hot-dry seasons respectively and 15% at Senqu during the post-rainy season. B. bigemina prevalence was highest at Elundini (18%) and Senqu (16%) during the post-rainy season and hot-wet season respectively. Cattle BCS was negatively correlated with E. ruminantium (P < 0.01; r = - 0.203), B. bovis (P < 0.01; r = - 0.125), and A. marginale (P < 0.01; r = - 0.122) seroprevalence. The PCV was negatively correlated with B. bigemina (P < 0.01; r = - 0.138) seroprevalence. On the other hand, E. ruminantium was positively correlated with Amblyomma hebraeum (P < 0.05; r = 0.112) infestation, while B. bovis (P < 0.05; r = 0.134) and B. bigemina (P < 0.05; r = 0.188) were positively correlated with Rhipicephalus microplus infestation, and B. bigemina (P < 0.05; r = 0.077) was positively correlated with Rhipicephalus decoloratus infestation. Our study reports for the first time the presence of R. microplus in the study area. Further research is, however, needed to better understand seroprevalence and the transmission mode of TBDs to cattle so that effective disease control measures can be developed.
