Dose-response Association between C-Reactive Protein and Risk of All-Cause and Cause-Specific Mortality: A Systematic Review and Meta-Analysis of Cohort Studies
A partir d'une revue systématique de la littérature publiée jusqu'en septembre 2019 (22 études), cette méta-analyse évalue l'association quantitative entre la protéine C-réactive et la mortalité par cancer
Purpose: To quantitatively assess the association between CRP and all-cause, cardiovascular disease (CVD), and cancer mortality, a dose-response meta-analysis was performed on data from cohort studies in general population. Methods: The published relevant articles were searched for in PubMed, Web of Science, and Embase until September 21, 2019. The pooled relative risk (RR) was estimated by random effects of generalized least square regression models. The dose-response relationship was modeled using restricted cubic splines. Results: Twenty-two articles were screened for the meta-analysis. Compared with the low CRP group, the pooled RR in the moderate CRP group was 1.30 (95% CI, 1.20–1.41) for all-cause mortality, 1.43 (95% CI, 1.22–1.68) for CVD mortality; the pooled RR in the high CRP group was 1.75 (95% CI, 1.59–1.92) for all-cause mortality, 2.02 (95% CI, 1.70–2.41) for CVD mortality, and 1.32 (95% CI, 1.21–1.45) for cancer mortality. Conclusions: This meta-analysis demonstrated the relationships between CRP and mortality were nonlinear for all-cause and CVD mortality, and were linear for cancer and non-cardiovascular mortality.
