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

We examined the influence of the CYP1A1 A4889G and T6235C, GSTM1 and GSTT1 polymorphisms, involved in carcinogen metabolism, on the head and neck (HN) squamous cell carcinoma (SCC) risk. DNA from 142 HNSCC patients and 142 controls was analysed by polymerase chain reaction (PCR)-restriction fragment length polymorphism or multiplex-PCR for the polymorphisms analyses. Excesses of the CYP1A1 4889AG+GG and 4889AG+GG plus GSTT1 null genotype were seen in patients with heavy tobacco habit compared with controls (41.9% versus 26.8%, P = 0.03; 26.2% versus 10.3%, P = 0.04, respectively). Carriers of the referred genotypes and heavy tobacco consumption were under a 2.0-fold and 2.8-fold increased risks for HNSCC than others, respectively. The CYP1A1 6235TC+CC plus GSTM1 and GSTT1 null genotypes were more common in pharyngeal SCC patients than in controls (5.3% versus 0.7%, P = 0.04). Carriers of the combined genotype had 16.0-fold increased risk for the disease than others. The frequency of one null genotype of the GSTM1 or GSTT1 gene was higher in patients with pharyngeal SCC and heavy smoking status than in controls (76.3% versus 57.7%, P = 0.04). Carriers of the referred genotype and heavy tobacco status had a 2.4-fold increased risk for pharyngeal SCC than others. In contrast, the CYP1A1 6235TC+CC genotype was more common in controls than in laryngeal SCC patients (35.9% versus 21.6%, P = 0.01). Carriers of the genotype had a 0.2-fold decreased risk for the disease than others. Our data present preliminary evidence that inherited combined CYP1A1 A4889G and T6235C abnormalities and GSTM1 and GSTT1 pathways are important determinants of HNSCC, particularly pharyngeal SCC in heavy smoking individuals from south-eastern Brazil.
