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

Enterococcus species are increasingly recognized as mastitis pathogens in dairy cows. Reliable species information is required for correctly defining the regional epidemiology of enterococcal mastitis, establishing its relationships with management variables, and understanding its impact on udder health. We investigated the species distribution of enterococci in bovine milk from subclinical mastitis (SCM) and clinical mastitis (CM) cases and full herd surveys (HS) using MALDI-TOF MS as identification method. A total of 21,864 milk samples from 106 dairy herds were routinely collected and analyzed according to the National Mastitis Council (NMC) guidelines over one year. Enterococcus spp. were found in 4.86% of CM, 5.05% of SCM, and 1.37% of HS milk samples. Overall, E. saccharolyticus was the most prevalent species (55.65%), followed by E. faecium (27.25%), and E. cecorum (5.51%), which showed a significant association with SCM (p-value = 0.0128). This study provides novel data on the Enterococcus species distribution in full herds survey and mastitis cases, highlighting the relevance of MALDI-TOF MS in refining enterococcal mastitis epidemiology, as true prevalence and species distribution may have been skewed by conventional biochemical tests.
