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

objectiveGenetic factors, in addition to oxidative stress factors, have been implicated in the development of chronic obstructive pulmonary disease (COPD). Multi-drug resistant-1 (MDR-1) is a gene located on chromosome 7 and the products of this gene protect lung tissue from oxidative stress. We searched the frequency of MDR-1 gene C/T polymorphism in patients with COPD and aimed to explain the association between MDR-1 gene and COPD development.

methods47 patients with COPD and 64 healthy control participants were placed in this study. DNAs were extracted from blood samples and MDR-1 amplification of DNA was performed using polymerase chain reaction and enzyme digestion techniques.

resultsThe frequencies of MDR-1 genotypes were found 17.0% for CC, 51.1% for CT and 31.9% for TT in the COPD group and 39.1% for CC, 53.1% for CT and 7.8% for TT in the control group. The distribution of MDR-1 gene C alleles were found 32.3% in COPD group and 67.7% in control group; T alleles were found 55.1% in COPD group and 44.9% in control group. There was statistically significant difference between the groups for genotype and allele frequency of MDR-1 gene (P = 0.001).

conclusionTT genotype of MDR-1 gene was significantly more frequent in COPD patients. MDR-1 gene C/T polymorphism may play a role in COPD development.
