Population vs Study population:::::::::::::::::

Population: যাদের উপর গবেষণার ফলাফল কে
generalize করা হয়
Study population: Sub group of population যেখান
আমরা sample select করি
Example:
Title: Quality of life of diabetic pts of Bangladesh
Population: All diabetic pts of Bangladesh
যদি এমন হয়,গবেষক বারডেম থেকে sample নিয়েছে তাহলে
Study population হবে: All diabetic patients
attending বারডেম in next
few months.

Population/ Target population/Reference population
All these 3 are synonymous.
Study population/ Sampling population
These 2 are synonymous

High total CK+CKRI>5 : source of CK-MB, Heart
High total CK+CKRI
