この研究はハイインパクトの可能性があります。 OEのAI駆動型ハイインパクト指標は、論文が掲載されたジャーナルと論文自体の科学的内容の両方からのシグナルを統合することで、論文が持つ可能性の高い影響力を推定します。 最先端の自然言語処理を用いて開発されたOEハイインパクトモデルは、ジャーナルのインパクトファクターのみよりも、研究の将来の引用実績をより正確に予測します。 これにより、臨床的に意義のある研究をより早く認識することが可能になり、読者は将来の診療を形成する可能性が最も高い論文に集中することができます。

Data from 18 RCTs were systematically reviewed to determine an optimal treatment focused on walking ability for patients suffering from neurogenic claudication (NC) due to lumbar spinal stenosis. The evidence is presented in this review demonstrated low quality evidence that prostaglandins improved walking, and that surgical direct decompression was no better than non-operative treatment in improving walking ability. Additionally, there was very low quality evidence that calcitonin was no better than placebo or paracetamol regardless of mode of administration, that epidural injections improved walking distance up to 2 weeks compared to placebo, and that surgical indirect decompression improved walking ability compared to non-operative treatment. Lastly, there was low- to very low-quality evidence that gabapentin or methylcobalamin improved walking distance, and that physical therapy was no better in improving walking ability compared to no treatment, oral diclofenac plus home exercises, or combined manual therapy and exercise.
