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

Bovine respiratory disease (BRD) is a leading cause of morbidity and antimicrobial use in calves. Laboratory diagnostics are limited by difficulty obtaining lower airway samples from live animals and the common presence of many BRD-associated bacteria in healthy calves, complicating culture interpretation. This study aimed to investigate the occurrence, clinical relevance, and antimicrobial resistance patterns of BRD-associated bacteria in calves from Norwegian fattening herds with enzootic pneumonia, and to evaluate agreement between upper and lower airway sampling sites. In a cross-sectional study, 88 calves from seven fattening herds were clinically scored and classified as healthy or diseased. Nasal swabs, nasopharyngeal swabs, bronchoalveolar lavage (BAL) fluid, and serum samples were collected for bacterial culture, antimicrobial susceptibility testing by disc diffusion, and serology.
