为了估计腹泻复发调查的不准确性，从1980年7月到1983年6月，孟加拉国特克纳夫学龄前儿童的母亲每周接受采访。因为一段插曲在一周中任何一天开始的可能性应该是相等的，所以我们能够量化观察到的任何偏差。结果显示，在任何一周的48小时召回期间之前，报告的腹泻发作平均减少34%。报告错误的数量(A)与召回期限的长短直接相关，(B)与腹泻的严重程度成反比，如发烧和运动频率所示。这一分析表明，孟加拉国每周的腹泻回忆调查将严重腹泻病例低估了20%-22%，将较轻病例低估了42%-44%。研究结果还表明，基于冗长回忆的发病率调查可能会在问题的严重性和抗击该问题所需的资源数量方面误导卫生规划者。
To estimate inaccuracy in a diarrhoea recal survey mothers of pre-school children in Teknaf, Bangladesh were interviewed every week from July 1980 through June 1983. Because the likelihood of an episode starting on any given day of the week should be equal, we were able to quantify any deviation observed. Results show an average of 34% less diarrhoea episodes reported prior to a 48-hour recall period in any week. The amount of reporting error was (a) directly related to the length of the recall period, and (b) inversely related to the severity of diarrhoea as indicated by presence of fever and frequency of motions. This analysis reveals that weekly diarrhoea recall surveys in Bangladesh underestimate severe diarrhoea cases by 20-22% and less severe cases by 42-44%. The findings also indicate that morbidity surveys based on lengthy recall are likely to mislead health planners with regard to the magnitude of the problem and the volume of resources required to combat it.
