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

backgroundThis study aimed to evaluate the relationship between the expression levels of selected integrin genes and proteins and cell differentiation, TNM stage, histological type and other variables potentially associated with the progression and dissemination of colorectal carcinoma (CRC).

methodsA total of 114 patients (63 men and 51 women) were treated for CRC between 2006 and 2009, including 25 (21.9%) TNM I, 39 (34.2%) TNM II, 34 (29.8%) TNM III, and 16 (14.1%) TNM IV. Regarding grade, 91 (79.8%) were grade II, 14 (12.2%) were grade III and nine (7.8%) were grade I. Reverse-transcription polymerase chain reaction (RT-PCR) and tissue microarray (TMA) methods were used to examine the expression levels of the genes ITGAV, ITGA3, ITGA5, ITGB5, and ITGA6, and their proteins, respectively.

resultsIn relation to TNM staging, ITGB5 and ITGA3 were over-expressed in stages III versus I. These results were confirmed by TMA analysis. In terms of age, ITGA5 was under-expressed according to RT-PCR, but over-expressed by TMA in patients over 60 years, while ITGA5 gene and protein levels were increased in mucinous carcinomas. In addition ITGAV gene and protein levels were elevated in tumors with neural invasion, and ITGA6 gene and protein were over-expressed in cases with venous invasion. All these results were significant at P < 0.05.

conclusionThe results of this study suggest that over-expression of some integrins is associated with TNM III stage, increased risk of vascular and neural invasion, and mucinous histology in patients with CRC.
