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

unlabelled

backgroundBladder cancer is a common malignancy in Egypt. A history of urinary tract infection can be considered as a risk factor for bladder cancer. Escherichia coli (E. coli) infection is responsible for 70% of urinary tract infection. This study aimed to evaluate the role of chronic E. coli infection during bladder carcinogenesis. In order to achieve this aim, we investigated the histopathological changes in bladder tissue and measured the level of nuclear factor kappa p65 (NF-κBp65), Bcl-2 and interleukin 6 (IL-6) in four groups each consisting of 25 male albino rats except of control group consisting of 20 rats. The first group was normal control group, the second group was infected with E. coli, the third group was administered nitrosamine precursor, and the forth group was infected with E. coli and administered nitrosamine precursor.

resultsThe histopathological examination revealed that E. coli infected group was able alone to produce some histopathological changes in bladder tissue and that nitrosamine precursor plus E. coli group showed highest incidences of urinary bladder lesions than the nitrosamine precursor group. NF-κBp65, Bcl-2 and IL-6 levels were significantly higher in nitrosamine precursor plus E. coli group than the other groups.

conclusionThese findings suggested that urinary bladder infection by E. coli may play a major additive and synergistic role during bladder carcinogenesis.
