13.你的回答非常谨慎，显示一定的疗效，是不是不能证实有疗效。(115)

确实，我的回答是出于谨慎考虑，因为针灸的疗效在不同的研究中结果不尽相同。一些临床试验表明，针灸在某些病症（如慢性疼痛、恶心等）的治疗上有积极作用，但也有研究显示其效果与安慰剂效应相当。因此，虽然可以看到针灸在某些情况下有一定的疗效，但并不能在所有情况下证实它的疗效，尤其是对于一些复杂或严重的疾病。

针灸的疗效因个体差异、病症类型和治疗方式的不同而有所差异，这也是为什么科学界对针灸的研究结果尚不一致。进一步的严格研究和实验验证仍然是确定其疗效的重要手段。

Indeed, my response is cautious because the results regarding acupuncture’s effectiveness vary across different studies. Some clinical trials have shown that acupuncture has positive effects in treating certain conditions like chronic pain or nausea, but other studies suggest that its effects are comparable to those of a placebo. Therefore, while acupuncture has demonstrated some efficacy in specific cases, it cannot be conclusively proven to be effective in all situations, especially for more complex or serious diseases.

The effectiveness of acupuncture varies depending on individual differences, the type of condition, and the treatment approach, which is why scientific research on acupuncture remains inconclusive. Further rigorous studies and experimental verification are needed to definitively establish its efficacy.
