Milk yield and lactation stage are associated with positive results to ELISA for Mycobacterium avium subsp. paratuberculosis in dairy cows from Northern Antioquia, Colombia: a preliminary study.
Article in Tropical animal health and production, 2016. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers, 1 of them a synthesis that pooled 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.
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
Paratuberculosis is a slow-developing infectious disease characterized by chronic granulomatous enterocolitis. This disease has a variable incubation period from 6 months to over 15 years and is caused by Mycobacterium avium subsp. paratuberculosis (MAP). Some studies have been conducted in cattle during the last decades in Colombia. However, those studies were designed using relatively small populations and were not aimed to establish prevalence. This study aimed to determine the MAP seroprevalence in selected dairy herds and to explore risk factors associated with the serology results. Serum samples and related data were collected from 696 randomly selected bovines in 28 dairy herds located in 12 different districts in one of the main dairy municipalities in Colombia (San Pedro de los Milagros). The samples were analyzed using a commercial ELISA kit. The information on risk factors was analyzed using a logistic regression. The apparent seroprevalence was 3.6 % (1/28) at the herd level and 2 % (14/696) at the animal level. The number of days in milk production between 100 and 200 days, and over 200 days as well as the daily milk production between 20 and 40 L/cow, and over 40 L/cow were associated with MAP seropositivity with odds ratios of 4.42, 3.45, 2.53, and 20.38, respectively. This study demonstrates the MAP seroprevalence in dairy herds from Antioquia, Colombia and the possible relationship between MAP seropositivity, milk yield, and lactation stage.
