Subject and researcher unaware of treatment status G. At a single point in time H. Followed all treatment/study procedures I. Do not have to complete treatment J. Subjects with common characteristics followed over time

Answer 1

Answer to the question)
Bias is an error that occurs due to systematic uncertainity like incorrect sampling , or wrong questionnaire and so on.

Hence Bias is matched to letter : B

Double blind implies during research neither the examiner nor the participants have any idea if they are being given the treatment or the placebo. This ensures that there is no biasedness in the final result due to any of the groups already knowing whether they have recieved the treatment or not

Hence the correct match for it is: F

In clinical trials subjects are assignment to the treatments randomly

hence correct match is E

Cohort means a group is formed that has same attributes. the group is studied together over a period of time to observe the changes in the attributes

The correct match is J

Confounding implies that some of the interaction effects are removed or confounded and hence the complete treatment is not used for it

the correct match is I

Corss-sectional is the type of study where the groups are studied simultaneously at a single point of time

Hence the correct match is G

Disease incidence tells us about the number of cases who got diseased in that time period, the number of new cases are highlighted by incidence rate

Hence the correct match is C

Intention to treat analysis deals with the risk factors distortion

Hence the correct match is A

Matching implies that comparison groups are formed based on similar factors like age group or income level or so on. Thus the groups are matched completely based on other factors.

Hence the correct match is D

Preprotocol implies one has to do all the treatments and procedures as per mentioned

Hence the correct match for it is H
