The effect of deep tubewell use on the incidence of childhood diarrhoea was assessed using a random effects negative binomial regression model.
采用随机影响负二项回归模型,评估深管井的使用对儿童发生腹泻的影响。

The risk of childhood diarrhoea was 46% lower in the 179 households that used a deep tubewell than in the 364 that used a shallow tubewell (P = 0.032).
179户使用深管井的家庭发生儿童腹泻的风险比364户使用浅管井的家庭低46%(P=0.032)。

At present, in the urban infrusture engineering, deep and big pit precipitation can be effectively solved with the method of tubewell precipitation.
