Concurrent Occurrence of Infectious Bursal Disease and Multicausal Respiratory Infections Caused by Newcastle Disease and Avian Metapneumovirus in Broilers.

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
Control strategy of respiratory complex infections should address precipitating and predisposing causative agents in general and immunosuppressive agents in particular. In both clinical and subclinical forms, infectious bursal disease virus (IBDV) is one of the most immunosuppressive diseases of young chickens. This study aimed to investigate the concurrent occurrence of subclinical infectious bursal disease (IBD) and multicausal respiratory complex infections caused by Newcastle disease virus (NDV) and avian metapneumovirus (aMPV) in broilers. In this study, 800 tissue samples (e.g., trachea, cecal tonsil, bursa of Fabricius, and spleen) and 400 sera samples were collected from broilers with confirmed respiratory signs selected from 20 broiler farms in west Azerbaijan province, Iran, from October 2018 to February 2019. Pathogens in the tissue samples were detected using RT-PCR for the VP2 gene of IBDV, F gen of NDV, and N gene of aMPV. The amplified products were sequenced afterward. At the end of the husbandry period, sera samples were used to detect antibodies against IBDV, aMPV, and NDV using ELISA and HI tests. Molecular results showed that the 45% (9/20), 30% (6/20), and 15% (3/20) of tissue samples were positive for IBDV, NDV, and aMPV, respectively. Regarding co-infection, 5% (1/20) of farm isolates were positive for IBD and ND, while 10% (2/20) of farms isolates were positive for IBD and aMPV. Co-infection of IBD, ND, and aMPV was not detected in farm isolates. Serological results indicated that the IBD co-infected flocks had almost higher (
