Serum Clara cell protein and atopic phenotype in children up to 2 years of age.
Article in Journal of clinical laboratory analysis, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundLow value of serum Clara cell protein (CC16) is associated with bronchial hyperreactivity in children.
objectiveTo evaluate the serum CC16 in relation to atopy and previously manifested LRTD.
methodsIn the population of 163 healthy 5- to 24-month-old children, atopy was determined by Phadiatop-infant (serum-specific IgE≥0.35 kUA/L), serum CC16 by ELISA, while data on previously manifested low respiratory tract diseases (LRTD) were collected from the Health Care Center database.
resultsIn atopic children, serum CC16 negatively correlated with age (r -.281, P=.041, n=53), while in nonatopic children, this correlation was positive (r .200, P=.036, n=110). Atopic ≥8-month-old children with previously manifested LRTD had lower level of CC16 (3.07 ng/mL) in relation to atopic children without LRTD at the same age (6.51 ng/mL), P=.029 (value of serum CC16≥4.8 ng/mL indicates atopic phenotype without LRTD 75% sensitivity, 87.5% specificity). In 8- to 24-month-old children with previously manifested pneumonia, serum CC16 was lower in atopic (2.9 ng/mL) in relation to nonatopic children (3.7 ng/mL), P=.029 (serum CC16 ≤3.4 ng/mL indicating atopy in the group of children with pneumonia, sensitivity 100%, and specificity 77%). Atopic 8- to 24-month-old children with previously manifested pneumonia had lower CC16 in relation to other atopic children in this age (P=.021) (for cutoff CC16≤3.4 ng/mL sensitivity 100%, specificity 77%), and also often chronic wheezing (atopic with pneumonia 83.3%, n=5/6 vs atopic without pneumonia 21.4%, n=3/14), P=.018.
conclusionLow serum CC16 is associated with previously expressed pneumonia and chronic wheezing in atopic children.
