Association between C-reactive protein gene +1059 G/C polymorphism and the risk of coronary heart disease: a meta-analysis
Bibliographic record
Abstract
BACKGROUND: C-reactive protein (CRP) gene +1059 G/C polymorphism has been reported to be associated with coronary heart disease (CHD) risk, but the results remain inconclusive. This meta-analysis was therefore conducted to clarify these controversies. METHODS: A comprehensive search was conducted to identify all case control studies on the association between CRP gene +1059 G/C polymorphism and CHD risk. All the related studies were further strictly selected according to the inclusion criteria. Meta-analysis was performed with STATA 10.1 (StataCorp, USA). The association was assessed by odds ratio (OR) and 95% confidence interval (CI); both Begg's funnel plot and Egger's regression test were used to assess the publication bias. RESULTS: This meta-analysis on a total of 13 studies comprising 6316 CHD cases and 4467 controls showed no significant association between CRP gene +1059 G/C polymorphism and CHD risk in the overall study (for C/C+C/G vs. G/G: OR = 1.01, 95% CI = 0.81-1.25, P = 0.96; for C/C vs. C/G+G/G: OR = 1.17, 95% CI = 0.77-1.77, P = 0.47; for C/C vs. G/G: OR = 1.17, 95% CI = 0.77-1.77, P = 0.47; for C allele vs. G allele: OR = 1.01, 95% CI = 0.81-1.24, P = 0.96). However, in the subgroup analysis by ethnicity, the results showed significant association between CRP gene +1059 G/C polymorphism and CHD risk among Caucasians (for C/C vs. G/G: OR = 2.54, 95% CI = 1.13-5.72, P = 0.02; C/C vs. C/G+G/G: OR = 2.45, 95% CI = 1.09-5.51, P = 0.03), but not among Asians and Africans (P > 0.05). CONCLUSION: CRP gene +1059 G/C polymorphism may be associated with increased CHD risk among Caucasians and more evidences need to validate the conclusion.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
