Anti-Outer membrane protein C antibodies in colorectal neoplasia.

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.
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
Sporadic colorectal cancer (CRC) represents an enormous problem worldwide. Large intestinal microbiota play an important role in the colorectal carcinogenesis. The aim of the study was to investigate anti-Outer membrane protein C (anti-OmpC) antibodies, aimed at porin C, which is embedded in the outer membrane of gram-negative bacteria, in patients with colorectal adenoma (CRA), CRC and controls. The study included 22 patients with CRA (11 men, 11 women, aged 26-79, mean 65 ± 12), 11 patients with CRC (9 men, 2 women, aged 50-83, mean 66 ± 11) and 45 controls, blood donors (24 men, 21 women, aged 20-58, mean 38 ± 10). Serum anti-OmpC antibodies were investigated by means of ELISA. Values of 0-20 U/mL were considered to be negative; values >25 U/mL were assessed as positive. A total of 9/11 (82 %) patients with CRC had positive anti-OmpC antibodies. Anti-OmpC antibodies were negative or grey-zone in 37/45 (82 %) controls. Serum anti-OmpC were found to be significantly higher in patients with CRC (median 42.4, interquartile range (IQR) 22.2) compared to controls (median 18.3, IQR 12.4), p < 0.001. No statistically significant difference in anti-OmpC was found between controls (median 18.3, IQR 12.4) and CRA patients (median 17.7, IQR 16.5), p = 0.326. Anti-OmpC were significantly higher in patients with CRC (median 42.4, IQR 22.2) compared to patients with CRA (median 17.7, IQR 16.5), p = 0.011. Positivity of anti-OmpC antibodies was found in patients with CRC, which supports the contribution of gram-negative large intestinal microbiota to the pathogenesis of CRC.
