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

backgroundThe pulmonary phenotype in patients with cystic fibrosis (CF), even in those with the same CF transmembrane conductance regulator (CFTR) genotype, is variable and must therefore be influenced by secondary genetic factors as well as environmental factors. Possible candidate genes that modulate the CF lung phenotype may include proinflammatory cytokines. One such protein is tumour necrosis factor alpha (TNFalpha), a member of the immune system.

methodsThree polymorphic loci in the promoter (-851c/t, -308g/a, -238g/a) and one polymorphic locus in intron 1 (+691g ins/del) of the TNFalpha gene were typed by a single nucleotide primer extension assay in CF patients and healthy controls. Spirometric data and first age of infection with Pseudomonas aeruginosa were collected retrospectively from patients' medical records.

resultsAn association was found between the TNFalpha +691g ins/del polymorphic locus and severity of CF lung disease. Patients heterozygous for +691g ins and +691g del were more likely to have better pulmonary function (mean (SD) forced expiratory volume in 1 second (FEV1) 79.7 (12.8)% predicted) than patients homozygous for +691g ins (mean (SD) FEV1 67.5 (23.0)% predicted; p = 0.008, mean difference 12.2%, 95% CI 3.5 to 21.0). Also, patients heterozygous for +691g ins and +691g del were more likely to have an older first age of infection with P aeruginosa (mean (SD) 11.4 (6.0) years) than patients homozygous for +691g ins (mean (SD) 8.3 (4.6) years; p = 0.018, mean difference 3.1 years, 95% CI 0.5 to 5.6). An association was also found with the -851c/t polymorphic locus. In the group of patients with more severe FEV1% predicted, a higher proportion of patients were homozygous for the -851c allele than in the other group of patients (p = 0.04, likelihood ratio chi2, odds ratio = 2.4).

conclusionTNFalpha polymorphisms are associated with the severity of CF lung disease in Czech and Belgian patients with CF.
