Seasonal fluctuation of lung function in cystic fibrosis: A national register-based study in two northern European populations.
Article in Journal of cystic fibrosis : official journal of the European Cystic Fibrosis Society, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 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
backgroundMany risk factors for lung disease in cystic fibrosis (CF) display a seasonal pattern yet it is unclear whether this is reflected in seasonal fluctuations in lung function.
methodsWe conducted a longitudinal study using CF registries in Denmark and the UK. 471 individuals with a median of 104 FEV
resultsWe found no significant cyclical seasonal variation in lung function in either country. The maximum variation in percent predicted FEV
conclusionIn both the UK and Denmark there may be small seasonal changes in lung function but this effect is not of clinical importance.
