Underestimation of respiratory symptoms by smokers: a thorn in chronic obstructive pulmonary disease diagnosis.
Article in NPJ primary care respiratory medicine, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 10 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
Primary care centers are ideal positions to identify chronic obstructive pulmonary disease (COPD). We determined the COPD prevalence among ever-smokers aged 40-65 years attending a 2-year program conducted in 22 Greek primary healthcare centers and made comparisons between genders, patients less than or greater than 55 years, and newly or previously diagnosed COPD patients. A total of 117 persons, after studying 1100 people, were diagnosed with previously unknown or known COPD, providing a COPD prevalence of 10.6% among the study population. In all, 7.5% of the participants were newly diagnosed with COPD. Women with COPD reported smoking less but experienced worse respiratory and depressive symptoms than men. A total of 19% of the COPD population below 55 years experienced wheezing and exacerbations more frequently than older patients. Newly diagnosed COPD patients were significantly younger, reported a significant burden of symptoms without seeking medical help. Primary health care has a crucial role in the early detection of COPD among unsuspecting smokers.
