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

Lung cancer (LC) is the leading cause of cancer-related mortality in developing as well as developed countries. Life style choices, particularly tobacco smoking, have been implicated as the main cause in the development of the LC. Despite the fact that majority cases of the LC occur among smokers, only 1-15% of smokers develop LC. In the present study, we have explored the role of genetic polymorphism, smoking habit and their association to LC in a cohort of north Indian population. The polymorphic genes explored were CYP1A1, GSTM1, GSTP1 and GSTT1 using techniques of Polymerase chain reaction (PCR), Restriction Fragment Length Polymorphism (RFLP), Real Time PCR (RT PCR), and gene sequencing. Genetic polymorphism was analysed in 253 normal participants (control) and 93 LC patients originating from Lucknow, India. Data were compared using odds ratio and Fisher Exact Test. We found that smoking increases the susceptibility to LC threefold (OR = 2.9; 95% CI: 0.9-2.8). The most significant risk for LC (OR = 3.2; 95% CI: 0.7-3.8) was found in the association of the homozygous variant of CYP1A1 gene at A2455G base change at Exon 7 (Val/Val) genotype. There was a marginally significant association between LC and GSTT1 null genotype (OR = 1.3; 95% CI: 1.0-1.7) while no significant risk association was found between GSTP1 polymorphism and LC. The present study demonstrates that the presence of null genotype of GSTM1/GSTT1 taken together with CYP1A1 (Val/Val) genotype increases the susceptibility to LC eightfold in comparison to CYP1A1 (Ile/Ile) and GSTM1/ GSTT1 genotype.
