Cytomegalovirus Seropositivity is Associated with Airflow Limitation in a Cohort of Veterans with a High Prevalence of Smoking.
Article in Chronic obstructive pulmonary diseases (Miami, Fla.), 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
backgroundCytomegalovirus (CMV) represents an understudied chronic infection, usually contracted early in life, that causes chronic immune system alterations which may contribute to airflow limitations in a cohort of veterans with a high prevalence of smoking. We studied 172 participants at-risk for and with airflow limitation with available CMV serology to assess the relationship between CMV infection and chronic obstructive pulmonary disease (COPD)-related outcomes.
methodsThe study cohort includes 172 veterans who are smokers with or at risk for the development of COPD. Clinical data were obtained by chart abstraction at enrollment. CMV affinity (ever-exposure) and avidity testing (length of exposure) were performed on plasma samples collected at enrollment. Bivariable and multivariable logistic regression was used to determine the relationship between both cytomegalovirus affinity and avidity and odds of prevalent airflow limitation (post-bronchodilator forced expiratory volume in 1 second to forced vital capacity ratio <0.70) at enrollment. In those with airflow limitation (n=84), bivariable and multivariable logistic regression was used to determine relationships between CMV serostatus and reported exacerbations of COPD over 2 years prior to enrollment.
resultsPositive CMV serostatus was independently associated with a 136% higher odds of airflow limitation (95% confidence interval 1.11-5.06,
conclusionsCMV serostatus is independently associated with airflow limitation in a cohort of veterans who smoke. Investigation into the timing of infection and alterations in cellular immunity caused by chronic CMV infection and smoking-related airways disease-related outcomes is warranted.
