Two Cases of Diffuse Alveolar Haemorrhage Attributable to Human Metapneumovirus Infection: A Case Report.

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
Diffuse alveolar haemorrhage (DAH) is a rare but potentially life-threatening syndrome with diverse etiologies. Human metapneumovirus (hMPV) infection has rarely been reported as a cause of DAH. We report two cases of DAH associated with hMPV infection in immunocompetent adults. In both patients, bronchoalveolar lavage fluid (BALF) showed progressively haemorrhagic returns and hemosiderin-laden macrophages, consistent with DAH. Multiplex polymerase chain reaction (PCR) using BALF detected hMPV, while extensive investigations excluded autoimmune, bacterial, and other viral causes. These cases suggest that lower respiratory tract infection with hMPV can be associated with DAH, even in immunocompetent adults. Screening for hMPV should be considered in cases of DAH of unknown aetiology, and multiplex PCR using BALF is a useful diagnostic tool.
