1 · What the graph read from 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.

2 · The registry

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

backgroundCigarette smoking aggravates asthma exacerbations, yet some patients with asthma continue to smoke.

aimsTo compare the quality of life of adult smokers and non-smokers with asthma.

methodsAsthma Quality of Life (AQLQ) questionnaires were administered to adult patients with asthma managed in primary care in Singapore. The survey also included data of their asthma status including symptom profiles. Independent two-sample t-test, ANCOVA model, χ2 test and ordinal logistic regression were used to compare the mean domain scores and the effect of smoking on nocturnal symptoms and awakening, respectively.

results357 adult asthma patients (183 non-smokers and 174 smokers) were recruited. Smokers were mainly male (p<0.001), single (p=0.008), and younger (mean age 30 years) (p=0.007). They were more affected by nocturnal cough and wheezing (p=0.016). After adjustment for age, gender, and asthma medications, the mean scores of the AQLQ 'symptoms' and 'emotional function' domains of smokers were 0.41 (95% CI 0.10 to 0.72) and 0.50 (95% CI 0.16 to 0.84) points lower than for non-smokers, with no statistical differences in the 'activity limitations' and 'exposure to environmental stimuli' domains.

conclusionsAdult patients with asthma who smoke are more affected by nocturnal symptoms, with lower 'emotional function' scores in the AQLQ.
