A linear analogue for rating pain with 10, 15 and 20 cm lines is significantly less variable than a 5 cm line (mean error of 15 cm line is 0-19%, 95% confidence limits for the group +/- 2% and an inood correlation between repeated ratins of a recalled pain distant in time. The variance of the rating is significantly less than the repeated rating of a random mark. The linear analogue rating of a constant pain stimulus is reproducible and changes in rating are likely to be real changes of opinion. Pethidine 150 mg intramuscularly had no significant effect, tested 30 minutes after the administration, on the accuracy or reproducibility of the analogue rating. A linear analogue seems a suitable method of recording the patient's opion of a severe pain such as that of labour.
使用10厘米、15厘米和20厘米线条来评定疼痛的线性模拟法，其变异性明显小于5厘米线条（15厘米线条的平均误差为0 - 19%，该组95%置信区间为±2%，且对相隔一段时间回忆起的疼痛进行重复评定时具有良好的相关性。评定的方差显著小于对随机标记的重复评定。恒定疼痛刺激的线性模拟评定具有可重复性，评定的变化很可能是真实的意见变化。肌内注射150毫克哌替啶，给药30分钟后进行测试，对模拟评定的准确性或可重复性没有显著影响。线性模拟似乎是记录患者对如分娩时剧痛看法的合适方法。
