Moiré topography was added to school scoliosis screening in Singapore in 1982. The results from 1342 topographs, assessed in isolation, were used to study the accuracy of the method in predicting the radiographic location and magnitude of scoliotic curves. Accuracy in identifying the site of the curve was 68% in the thoracic spine, 54% in the thoracolumbar spine, and 15% in the lumbar region. There were 12.7% false-positive results and 4.3% false negatives. Of patients with a deviation of one moiré fringe, 76.5% had a curve of 15 degrees or less; of those with a deviation of four moiré fringes, 69% had a curve greater than 26 degrees. The prediction of the Cobb angle was less accurate when there was a deviation of two or three fringes. It is suggested that moiré topography as a screening device should be reserved for use in the second tier of screening, since the forward-bending test is an effective and cheap method for the first tier of a mass school-screening programme.
1982年，莫尔条纹地形测量法被纳入新加坡学校脊柱侧弯筛查。对1342份单独评估的地形测量结果进行分析，以研究该方法预测脊柱侧弯曲线的影像学位置和严重程度的准确性。在胸椎，确定侧弯部位的准确率为68%；在胸腰椎，准确率为54%；在腰椎，准确率为15%。假阳性结果为12.7%，假阴性结果为4.3%。对于莫尔条纹偏差为1条的患者，76.5%的侧弯角度为15度或更小；对于莫尔条纹偏差为4条的患者，69%的侧弯角度大于26度。当条纹偏差为2条或3条时，对Cobb角的预测准确性较低。建议莫尔条纹地形测量法作为一种筛查手段，应留作二级筛查使用，因为前屈试验是大规模学校筛查计划一级筛查的一种有效且廉价的方法。
