The acupuncture treatment situation was beneficial to the majority of people with low back pain. This was shown by the use of short-term controls and long-term controls, although the latter were not intended in the study design. After acupuncture, there was a 51% pain reduction in the average pain score in the Immediate Treatment Group. The short-term controls, the Delayed Treatment Group, had no reduction whatsoever in their pain scores at the comparable followup period. Later, the Delayed Treatment Group bere also treated by acupuncturists, and reported 62% less pain. When these two treatment groups were compared at 40 weeks with long-term controls (Inadequate Treatment Group), the Inadequate Treatment Group still had the same pain scores, on the average, as when they enrolled in the study. Both treatment groups, on the average, had 30% lower pain scores. Furthermore, 58% of the treatment groups felt that they were definitely improved at 40 weeks, while only 11% of the Inadequate Treatment Group felt definitely improved at 40 weeks.
针灸治疗情况对大多数腰痛患者有益。这一点通过短期对照组和长期对照组得到了体现,尽管长期对照组并非本研究设计所预期的。针灸治疗后,即时治疗组的平均疼痛评分降低了51%。短期对照组,即延迟治疗组,在可比的随访期内疼痛评分没有任何降低。后来,延迟治疗组也接受了针灸师的治疗,报告称疼痛减轻了62%。当将这两个治疗组在40周时与长期对照组(不充分治疗组)进行比较时,不充分治疗组的平均疼痛评分仍与他们进入研究时相同。两个治疗组的平均疼痛评分均降低了30%。此外,58%的治疗组感觉在40周时病情肯定有所改善,而在40周时只有11%的不充分治疗组感觉病情肯定有所改善。
