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
objectiveTo study the role of serum neutrophil elastase (NE) level in acute exacerbation of asthma in preschool children.
methodsA total of 85 preschool children who were diagnosed with asthma between January 2008 and January 2010 were classified into acute exacerbation group (n=44) and non-acute exacerbation group (n=41). Thirty-five children who received physical examination served as the control group. The enzyme-linked immunosorbent assay was used to determine the serum levels of NE and interleukin-8 (IL-8). The receiver operating characteristic (ROC) curve was used for NE evaluation.
resultsBoth the acute and non-acute exacerbation groups had higher serum levels of NE and IL-8 than the control group, and the acute exacerbation group had significantly higher serum levels of NE and IL-8 than the non-acute exacerbation group (P<0.05). The serum level of NE was positively correlated with that of IL-8 (r=0.48, P<0.05). With serum NE level >27.73 μg/L as the cut-off value for diagnosing acute exacerbation of asthma, the sensitivity was 65.9%, the specificity was 95.1%, and the area under the ROC curve was 0.87 (P<0.01).
conclusionsThe determination of serum NE level in preschool children with asthma helps to diagnose the acute exacerbation of asthma.
