Two researchers drew their conclusions from a survey of a week's complaints about dampness at five local authorities.
But each month, researchers drew blood from the children and examined the white blood cells to see if any were normal.
In the former, the researcher can draw very strong inferences from comparisons between randomized groups.
With these approaches, the researcher should draw upon their own knowledge and the research to label the narrative.
The researchers drew on information gathered in a national health survey of more than 43,000 people.
The researchers drew on data involving more than 4,000 people from four cities who were periodically examined over the course of the study.

Here, the researchers draw all the pieces from the study together to present the whole picture.
The researchers did not draw conclusions about the physiological link between long sleep and diabetes.
Dr. Read cautioned that the researchers drew their conclusions from a relatively small number of trials.
