ERCC1 and XPD/ERCC2 polymorphisms' predictive value of oxaliplatin-based chemotherapies in advanced colorectal cancer has an ethnic discrepancy: a meta-analysis.

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
Our purpose is to evaluate the predictive value of the genetic polymorphisms of Excision repair cross-complementing group 1 (ERCC1) and xeroderma pigmentosum group D/excision repair cross-complementing group 2 (XPD/ERCC2) in patients with advanced colorectal cancer receiving oxaliplatin-based chemotherapy, and we performed a meta-analysis in order to obtain a more precise estimation for a more optimizing individual chemotherapy. The relevant cohort studies were identified by searching the electronic databases of MEDLINE, EMBASE, and CNKI. We used ''colorectal,'' ''cancer,'' ''carcinoma,'' ''ERCC1,'' ''XPD or ERCC2,'' ''polymorphism,'' ''oxaliplatin,'' ''treatment,'' or ''chemotherapy'' as key words. Inclusion criteria were patients with advanced colorectal cancer receiving oxaliplatin-based chemotherapy, evaluation of polymorphism of ERCC1 and XPD/ ERCC2, and overall response rate (ORR). In this meta-analysis, a total of seven studies were selected according to the inclusion criteria. Five studies investigated ERCC1 codon 118 polymorphisms and three studies evaluated XPD/ERCC2 codon 751 polymorphisms. For ERCC1 codon C118T polymorphism, the ORR to oxaliplatin-based chemotherapy in patients with C/C wild genotype was 77.27% and it was 69.30% for C/T and T/T variant genotype. The pooled odds ratio (OR) for C/C wild-type vs. C/T and T/T genotype was 1.11 (95% CI, 0.86-1.42; P = 0.42). For XPD/ERCC2 Lys751Gln polymorphism, the response rate was 86.58 and 67.57% in patients with the A/A and either one or two C alleles (A/C or C/C) respectively, and the pooled OR was 1.15 (95% CI, 1.01-1.30; P = 0.03). Furthermore, we chose subgroup analysis in order to find the difference between the Caucasian and Asian ethnicity. The results indicated that Oxaliplatin sensitivity was significantly associated with ERCC1 C118T polymorphism in Asian people. XPD/ERCC2 Lys751Gln polymorphism had the predictive value especially for the patients from the America and Europe.
