Metric Options: CountsSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Review Description
Objective The present study aimed to evaluate the relationship between UGT1A1*28 gene polymorphism and the prevalence of neutropenia in patients with colorectal cancer treated with irinotecan. Method Thirteen studies were included. These papers were selected from the Virtual Health Library, Scientific Electronic Library Online, International Health Sciences Literature and PubMed, and their data were collected and evaluated using the BioEstat 5.3 software (BioEstat, Belém, PA, Brazil). Results Three genotypes were analyzed, namely 6/6 (wild type), 6/7, and 7/7. In total, 2,146 patients were included in the present study; of these, 55.6% (n = 1,193) had 6/6 genotype, 37.3% (n = 801) were heterozygous (6/7), and 7.1% (n = 152) had the 7/7 genotype. A total of 1,672 (77.9%) patients displayed mild neutropenia, whereas 474 (22.1%) had severe neutropenia. When contrasting the 6/7 and 7/7 genotypes with the 6/6 genotype using statistical tests for meta-analysis, patients with the 7 allele, either in homozygosis or heterozygosis, presented higher risk of developing severe neutropenia than patients with the 6/6 genotype (odds ratio = 1.559; 95% confidence interval = 1.163-2.090; p = 0.003). Conclusion The analysis of the UGT1A1*28 gene polymorphism can aid the choice of treatment for patients with colorectal cancer in personalized medicine, increasing the chances of therapeutic success.
