A study on UHPLC-MS/MS analyses of DNA and RNA oxidative damage metabolites in patients with cervical carcinoma: 8-oxoG in urine as a potential biomarker of cervical carcinoma.

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
Objective: The purpose of this study was to compare the levels of 8-oxoG and 8-oxodG in urine of patients with cervical carcinoma and healthy women to evaluate their influences on cervical carcinoma. Methods: In this study, urine samples were collected from 70 patients with cervical carcinoma, 24 patients with one-year follow-up, and 100 healthy women. The contents of 8-oxodG and 8-oxoG in urine were assayed by ultra-high performance liquid chromatography tandem mass spectrometry (UHPLC-MS/MS). Results: The levels of 8-oxoG and 8-oxodG were higher in patients with cervical carcinoma (P < 0.000), while AUC of 8-oxoG and 8-oxodG was higher than 0.7. Specifically, the high-risk HPV (HR-HPV) positive group had higher 8-oxoG levels (P < 0.000), but there was no difference in 8-oxodG levels. Yet, 8-oxoG level was associated with lymphatic metastasis, lymph-vascular space infiltration (LVSI) and stromal infiltration, while 8-oxodG level was affected by the differentiation degree and stromal infiltration. According to statistics, the distinct cut-off index of lymphatic metastasis was 7.282 nmol/mmol creatinine. After operation, the concentrations of 8-oxoG and 8-oxodG dropped significantly (8-oxoG P < 0.000, 8-oxodG P = 0.004). Except for chemotherapy group, the urinary 8-oxoG dose of all treatment groups and 8-oxodG dose of chemo-radiotherapy group declined obviously. Conclusions: 8-oxoG may be a potential biomarker for cervical carcinoma.
