Pulmonary Function and Respiratory Diseases in Different Genotypes of Alpha-1 Antitrypsin Deficiency.
Article in Turkish thoracic journal, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
objectiveRespiratory disease is the major cause of morbidity and mortality in patients with alpha-1 antitrypsin deficiency, mainly in homozygous PI*ZZ individuals. However, this association is uncertain in subjects with other deficiency genotypes. The objective of this study was to assess, in the context of alpha-1 antitrypsin deficiency, the existence of further risk factors that have been associated with respiratory diseases. MATERIAL AND
methodsLung function was assessed by spirometry in a sample of 1334 patients with a known genotype for the SERPINA1 gene whose serum alpha-1 antitrypsin levels had been previously determined. Patients with a normal genotype (PI*MM) were compared to 389 patients carrying a deficiency allele.
resultsStatistically significant associations were detected between (i) PI*ZZ genotype and abnormal FEV1 values (χ2 = 26.45; P <.0002), FEV1/FVC (χ2 = 14.8; P < .02) or forced mid-expiratory flow 25%-75% (χ2 =22.66; P < .0009); (ii) chronic obstructive pulmonary disease and PI*ZZ odds ratio: 26.5; 95% CI: (2.6-265.9); P <.005 and or PI*SS genotype odds ratio: 9; 95% CI: (2-40.1); P < .004; (iii) prevalence of COPD in PI*MZ subjects and smoking habit (P < .01), low body weight (P < .01) or older age (P < .0001).
conclusionThe PI*ZZ and PI*SS genotypes seem to be associated with the prevalence of chronic obstructive pulmonary disease. Tobacco use, low body weight, and older age are risk factors that increase the probability of prevalence of chronic obstructive pulmonary disease by up to 70% in PI*MZ individuals.
