[Prevalence and characteristics of chronic obstructive pulmonary disease in non-smokers].
Article in Atencion primaria, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers, 1 of them a synthesis that pooled 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.
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
objectiveThe objective of the study was to know the profile of patients diagnosed with chronic obstructive pulmonary disease (COPD) and who have never been smokers.
designA transversal study. LOCATION: Primary Care Centre of Pla d'Urgell (Primary care setting in Lleida, Spain).
participants512 patients older than 40 years with COPD from Primary Care Centre of Pla d'Urgell with a compatible spirometry [forced expiratory volume in one second (FEV MAIN MEASUREMENTS: The dependent variable was de COPD in non-smokers and the independents were variables collected from the information on the respiratory clinical history, the risk factors of the patients and on quality of life. We designed a predictor model of COPD in non-smokers compared to smokers.
results33.2% of COPD patients had never been smokers, 59.4% of whom were women. The average FEV
conclusionsThe study evidences a high proportion of non-smokers in COPD patients. Our study aims that older women with less severity would be associated with an increased risk of COPD in non-smokers. It seems to indicate that COPD in non-smokers would appear at later ages and would be milder than smoking-related COPD.
