The variability of tuberculin skin test readings among six trained and experienced readers was evaluated using a modified sliding caliper method. Each of 537 tests were read independently by two readers. There were 23 disagreements between paired readers resulting in an overall interobserver reliability of 95.7 per cent. In 82 per cent of the paired readings the results were different by 2 mm or less. The observer lack of variability was likely due to the training and experience of the readers.
采用改良游标卡尺法评估了六位训练有素且经验丰富的阅片者之间结核菌素皮肤试验读数的变异性。537项检测中的每一项均由两位阅片者独立读取。配对阅片者之间存在23处分歧，观察者间总体可靠性为95.7%。在82%的配对读数中，结果差异在2毫米或更小。观察者变异性低可能归因于阅片者的培训和经验。
