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

Numerous enzymes, including Cytochrome P450s (phase I) and Glutathione-S-transferases (phase II), are involved in the metabolic activation and detoxification of carcinogens. Epidemiological studies have consistently demonstrated that bladder cancer is strongly associated with cigarette smoking, and the risk for the development of this neoplasia may be modified by individual differences in carcinogen-metabolizing genes. We investigated the relationship between polymorphisms in the CYP1A1, GSTM1, GSTT1, and GSTP1 genes in a case-control study with 100 bladder cancer patients and 100 controls matched for age, gender, race, and smoking status. The GSTM1, GSTT1, CYP1A1 (A2455-->G), and GSTP1 (A313-->G) genotypes were determined using a multiplex PCR, an allele specific PCR, and a restriction fragment length polymorphism-PCR method. The present case-controlled association study did not detect any positive or negative association for the GSTM1 and GSTP1 genes [odds ratios (OR) = 1.35; 95% confidence interval (CI) = 0.76-2.41 and OR = 0.75; 95% CI = 0.41-1.38, respectively]. Notably, the genes GSTT1 and CYP1A1 exhibited a statistically significant association with bladder cancer (OR = 1.77; 95% CI = 1.01-3.12 and OR = 1.99; 95% CI = 1.07-3.73). No differences for GSTM1 and GSTP1 genotype prevalence between the bladder cancer cases and the controls were observed, however, the null genotype for the GSTT1 gene and the A/G and G/G variants of the CYP1A1 gene may contribute to the development of bladder cancer.
