The prevalence of heifer mastitis and its associated risk factors in Huanggang, Central China.
Article in Tropical animal health and production, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
The purposes of this study were to determine the prevalence of heifer clinical mastitis (HCM) and heifer subclinical mastitis (HSCM), isolate HCM-causing bacteria, and assess the association of some risk factors in Huanggang, Central China. A total of 1,374 lactating heifers from three dairy farms were examined in the present study; 22.64% of heifers were positive for mastitis, out of which, 3.86 and 18.78% were with HCM and HSCM, respectively. Of the 67 HCM samples, 91.05% were single growth, 7.46% mixed growth, and 1.49% no bacterial growth. Coagulase-negative staphylococci (CNS) accounted for 30.98% of the isolates followed by Escherichia coli (29.58%), Staphylococcus aureus (16.9%), and Streptococcus uberis (11.27%). Logistic regression analyses showed that heifer milk yield lower than 3 L had the highest prevalence of HCM compared to heifer milk yield of more than 3 L (P < 0.01), and prevalence of HCM was significantly high in heifers with the presence of teat lesions (P < 0.01). Moreover, the heifer milk yield lower than 3 L had the highest prevalence of HSCM compared to heifer milk yield of more than 3 L (P < 0.01). These two factors were significantly associated with the occurrence of heifer mastitis, which needs to be considered in the prevention and control strategies of the disease.
