1 · What the graph read from 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.

2 · The registry

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 investigate the fractional exhaled nitric oxide (FeNO) normal value of healthy children, and provide a reliable theoretical basis for clinical diagnosis.

methods481 healthy children aged 6-15-y-old in three primary schools in Chengdu were subjected for FeNO detection. Through the statistical analysis, the upper limit normal value of FeNO among the healthy children was obtained, and the related influencing factors of FeNO value were analyzed.

resultsAmong the 481 heathy children, the geometric mean value of FeNO was 14.59 ppb (minimum value was 5 ppb, maximum value was 69 ppb), and the upper limit of normal value was 28 ppb. The age, height, and weight all have significant correlations with FeNO.

conclusionThe upper limit of FeNO in healthy children aged 6-15-y-old was 28.0 ppb. Inflammation in the airway was suggested when the value of FeNO exceeds 28.0 ppb. Furthermore, the influencing factors such as age, weight, height must be considered.
