Plasma surfactant protein-B is elevated in infants with respiratory syncytial virus-induced bronchiolitis.
Article in Pediatric research, 1999. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Respiratory syncytial virus (RSV) is the most frequent cause of bronchiolitis. However the pathophysiology of bronchiolitis is unclear. Leukocytes, especially neutrophils, may play an important role in the pathogenesis of bronchiolitis. Whereas we have previously shown that neutrophils augment epithelial leakage and detachment in RSV infection in vitro, it is unknown whether epithelial damage occurs in vivo in infants with RSV bronchiolitis. We hypothesized that respiratory epithelial damage occurs in infants with RSV bronchiolitis and that surfactant proteins leak into the circulation. The plasma concentrations of surfactant protein-A and surfactant protein-B in infants with RSV bronchiolitis were measured by ELISA. Plasma immunoreactive surfactant protein-B in infants with RSV bronchiolitis was markedly higher than that in matching controls. Our study suggests that alveolocapillary permeability is increased in infants with RSV bronchiolitis in vivo and that surfactant protein-B may be a sensitive marker for lung injury in such infants.
