The Effects of Aging on Exhaled Nitric Oxide (FeNO) in a North African Population.
Article in Lung, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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 determine and explain the effect of age on exhaled nitric oxide values in North African healthy subjects aged from 5 to 83 years.
designProspective cross-sectional study.
methodsVolunteer children adults and elderly healthy subjects were included. A medical questionnaire was used to assess several subject characteristics. The levels of exhaled fraction of nitric oxide (FeNO) were measured by Medisoft HypAir FeNO method. Spirometry function test was done after the FeNO measurement. The following parameters were measured: forced vital capacity (FVC, L); 1st second forced expiratory volume (FEV
resultsA significant increase in FeNO is noted between groups with respective age ranges of (5, 17) and (17, 25) years with a breakpoint at 1,397,034 years. A significant decrease of FeNO is noted between groups with respective age ranges of (45, 55) and (55, 65) years with a breakpoint at 6,366,052 years. No statistical significant difference was found between females' and males' means FeNO data. Finally, SEL, obesity status, and hypertension contribute significantly in the variations of FeNO values.
conclusionThe development and aging of the lung touched non-respiratory functions and so modified FeNO values in healthy North African subjects.
