| Abstract |
Published studies showed controversial findings about the relationship between glutathione S-transferase M1 (GSTM1) null genotype and clinical outcomes of patients with colorectal cancer. We performed a meta-analysis to quantitatively assess the association between GSTM1 null genotype and prognosis of patients with colorectal cancer. We systematically searched Pubmed, Embase, and Web of Science to identify prospective or retrospective cohort studies assessing the association of GSTM1 null genotype with overall survival (OS) or disease-free survival (DFS) in colorectal cancer. The hazard ratios (HRs) and 95 % confidence intervals (95 % CIs) were used to assess the association of GSTM1 null genotype with OS or DFS. Finally, 15 studies from 14 publications with 4326 colorectal cancer patients were included into the meta-analysis. There was no heterogeneity in the meta-analysis relating OS (I (2) = 0 %) and DFS (I (2) = 0 %). Overall, GSTM1 null genotype was significantly associated with poor OS in patients with colorectal cancer (HR = 1.18, 95 % CI 1.07-1.30, P = 0.001). In addition, GSTM1 null genotype was also significantly associated with poor DFS in patients with colorectal cancer (HR = 1.15, 95 % CI 1.03-1.28, P = 0.015). No obvious risk of publication bias was observed. GSTM1 null genotype is significantly associated with poor OS and DFS in patients with colorectal cancer, which suggests that GSTM1 null genotype confers poor effect on the prognosis of colorectal cancer. |

Attention Score in Context
This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 03 February 2016.
All research outputs
#20,303,950
of 22,842,950 outputs
Outputs from Tumor Biology
#1,834
of 2,622 outputs
Outputs of similar age
#333,441
of 396,541 outputs
Outputs of similar age from Tumor Biology
#145
of 221 outputs
Altmetric has tracked 22,842,950 research outputs across all sources so far. This one is in the 1st percentile – i.e., 1% of other outputs scored the same or lower than it.
So far Altmetric has tracked 2,622 research outputs from this source. They receive a mean Attention Score of 2.2. This one is in the 1st percentile – i.e., 1% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 396,541 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 1st percentile – i.e., 1% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 221 others from the same source and published within six weeks on either side of this one. This one is in the 1st percentile – i.e., 1% of its contemporaries scored the same or lower than it.
