Expert writing Tips

Best practice

When using "defined duration", ensure the definition or the method of defining the duration is clear to avoid ambiguity. For example, "The study had a "defined duration" of six months, starting from the patient's initial diagnosis."

Common error

Avoid assuming the reader understands how the duration is defined. Always explicitly state the criteria or method used to determine the "defined duration". Don't say, for example, just "The experiment had a "defined duration""; instead, say, "The experiment had a "defined duration" of 48 hours, measured from the introduction of the catalyst."
