The etiology of diarrhoea has been assessed in studies from many countries, but because of incomplete laboratory methodologies employed, and sampling from only hospital- or clinic-based patients, the results of such studies are often only partially valid.
But the data were incomplete, used questionable methodology and omitted to mention the most important test of all – how G8 countries were doing against the pledge made at Gleneagles four years ago to double aid by $50bn.

As a result of our methodology and incomplete survey of the canyon, our estimate of the trails used by feral horses in Coyote Canyon represents a minimum estimate.
Identification of the design proved a complex task, and it is therefore possible that some study may have been misclassified as regards design, due to an incomplete description of the methodology used.
