| Abstract |
Consumption diets of high glycemic index (GI) and glycemic load (GL) may increase the risk of breast cancer. We aimed to conduct a meta-analysis of prospective cohort studies to evaluate the associations between dietary GI and GL and risk of breast cancer. We searched the PubMed database for relevant studies through November 2010, with no restrictions. We included prospective cohort studies that reported relative risk (RR) with 95% confidence intervals (CIs) for the associations of dietary GI and GL with breast cancer risk. Summary RRs were calculated using both fixed- and random-effects models. We identified 10 prospective cohort studies eligible for analysis, involving 15,839 cases and 577,538 participants. The summary RR of breast cancer for the highest GI intake compared with the lowest was 1.08 (95% CI: 1.02-1.14), with no evidence of heterogeneity (P = 0.72, I (2) = 0%). For GL, the summary RR was 1.04 (95% CI: 0.95-1.15), and substantial heterogeneity was observed (P = 0.02, I (2) = 55.6%). The GI and GL and breast cancer associations did not significantly modified by geographic region, length of follow-up, number of cases, or menopausal status at baseline. Dose-response analysis was not performed due to limited number of eligible studies. There was no evidence of publication bias. In summary, the present meta-analysis of prospective cohort studies suggests that high dietary GI is associated with a significantly increased risk of breast cancer. However, there is no significant association between dietary GL and breast cancer risk. |

Attention Score in Context
This research output has an Altmetric Attention Score of 10. 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 11 July 2019.
All research outputs
#3,086,826
of 22,760,687 outputs
Outputs from Breast Cancer Research and Treatment
#498
of 4,652 outputs
Outputs of similar age
#19,629
of 181,257 outputs
Outputs of similar age from Breast Cancer Research and Treatment
#5
of 43 outputs
Altmetric has tracked 22,760,687 research outputs across all sources so far. Compared to these this one has done well and is in the 86th percentile: it's in the top 25% of all research outputs ever tracked by Altmetric.
So far Altmetric has tracked 4,652 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 7.2. This one has done well, scoring higher than 89% of its peers.
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 181,257 tracked outputs that were published within six weeks on either side of this one in any source. This one has done well, scoring higher than 89% of its contemporaries.
We're also able to compare this research output to 43 others from the same source and published within six weeks on either side of this one. This one has done well, scoring higher than 88% of its contemporaries.
