OBJECTIVES
The main objective of this study is to analyse the impact of green tea on mental health of an
individual who were suffering from depression and compare its effects with placebo which is an inert
substance which is used in treatments.
Objectives which will help in addressing the studies and their outcomes are:
 To address effect of green tea on all the participants suffering from depression.
 To compare the effect of green tea with placebo on depression individuals.
 To analyse the outcome of green tea and placebo to reduce the symptoms of depression.
ELIGIBILITY CRITERIA
There are few, study as well as report characteristics based on which eligibility criteria of the
study is decided. Study characteristics consist of following criteria such as: population, intervention,
comparison, outcomes, study design and time frame. Report characteristics consist of following criteria
such as: considered years, language etc. This eligibility criteria helps in increasing the reliability and
validity of the study.
Eligibility criteria of the study includes: Population which is to be focused for the study are
people who are suffering from depression. Main intervention which is to be focused in the study is green
tea. Main comparison of green team will be done by placebo which is an inert substance which is used in
treatments. Clinical outcomes of the study is to reduce the symptoms of depression. Study design to be
followed in this study is randomised controlled trials where subjects were randomly assigned within the
groups. Time frame of the study is studies published within 10 years in English language, non randomised
controlled trials were excluded.
RISK OF BIAS IN INDIVIDUAL STUDIES
This document focuses on studying the effectiveness of the study as well as compares their
effectiveness as well. This is basically done by assessing the risk bias of individual studies. There are
various methods which help in accessing this risk bias of individual studies. These methods will be
applied at the study level and will also help in utilising the way in which information will be used in
synthesis. It helps in assessing the strength of body of evidence. Criteria for accessing risk should be
completely segregated from applicability, precision etc. First of all study design labels should not be used
as proxy for assessing risk. For this evaluation of study was also done to increase the reliability and
validity of all the outcome measures of the study.
