Abstract
目的：探讨肿瘤坏死因子-α-308（tumor necrosis factor-alpha-308,TNF-α-308）基因多态性与慢性牙周炎（chronic periodontitis,CP）易感性的关系。方法：计算机检索PubMed、EMbase、CNKI、CBM、VIP和万方数据,检索时限均为建库至2013年10月。按照纳入与排除标准筛出关于TNF-α-308G/A基因多态性与CP易感性相关的病例-对照研究或队列研究。对纳入研究采用Newcastle-Ottawa量表进行质量评价。采用RevMan 5.2.0和Stata 12.0软件进行统计分析。结果：共纳入18个研究,1 420例CP患者,1 538例健康对照。Meta分析结果显示：①TNF-α-308G/A基因多态性与CP相关性：等位基因遗传模型A vs.G（OR=1.05,95%CI=0.83~1.34,P=0.68）、加性遗传模型AA vs.GG（OR=1.35,95%CI=0.78~2.34,P=0.28）、显性遗传模型AA＋AG vs.GG（OR=1.02,95%CI=0.79~1.33,P=0.88）、隐性遗传模型AA vs.AG＋GG（OR=1.42,95%CI=0.82~2.45,P=0.21）;②以人种、严重程度、吸烟情况为亚组进行分层分析,结果显示TNF-α-308位点的多样性在不同人群中也无明显相关性（P〉0.05）。结论：现有证据显示,TNF-α-308基因多态性可能与CP易感性无关。由于纳入研究数量有限,上述结论尚需开展更多高质量、大样本的随机对照试验加以验证。

How this classification was reachedexpand
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; both teacher heads agree on what is shown here.
