Prevalence, aetiology and host and management factors associated with bovine mastitis in dairy cows in Zoba Anseba, Eritrea: a cross-sectional study.
Article in BMC veterinary research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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.
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
From 47 dairy farms located in the Anseba Region of Eritrea, 222 cows were randomly selected for a questionnaire survey, examined for signs of clinical mastitis and milk samples tested for subclinical mastitis using the California mastitis test (CMT). Twenty cows (9%) were deemed to have clinical mastitis (CM), because they had visible clinical signs or visible changes in milk samples. Of the 202 cows tested by the CMT, 156 (77.23%) had a score of 1 or above at least in one quarter and were deemed to have subclinical mastitis (SCM). SCM was significantly more frequent in exotic breeds than in cross or indigenous breeds (p < 0.001) and cows with poor body condition compared to cows with good body condition (p = 0.025). CM was significantly more frequent in cows with a history of clinical mastitis (p = 0.004). SCM was significantly more frequent in farms that keep dung inside the compound (p = 0.004), do not milk cows with mastitis last (p < 0.01), use earthen floor (p < 0.01), do not routinely use mastitis test (p < 0.001), have intensive system of production and in farms with frequent tick infestation of the udder (p < 0.001). From 20 CM-positive and 153-SCM-positive composite milk samples tested, 29 isolates of Staphylococcus aureus, 23 Enterococcus faecium and 20 Streptococcus species, including 8 Streptococcus agalactiae were isolated. Of the 13 isolates of S. aureus tested, all were resistant to tetracycline, 11 to sulfonamides and 10 to penicillin. Two Streptococcus agalactiae isolates tested were resistant to tetracycline and penicillin.
