 Students, now we are going to study one example of a systematic literature of you. This study was conducted by myself and my team. The authors who conducted this study was Dr. Sara Dizvi-Jafri. She belongs to the Forman Christian College. I am Dr. Kaisa Khalid Mahmood from Punjab University. Dr. Malik Mohammad Sohail from the University of Chakwal. Dr. Mohammad Asim from Agha Khan University and Jane Barlow from the University of... Professor Jane Barlow is basically from the University of Oxford and she supervised this study. This study is about systematic review of Pakistani women's health outcomes from primary care interventions. This was a narrative synthesis of the women's health outcomes from primary care interventions in Pakistan. We conducted this study in 2022 and we published it in BMJ, Open One of the Reputed Public Health Journal. So what were the objectives of this study? The first objective of this study was to synthesize the available evidence regarding the effectiveness of primary care based interventions aimed at improving women's mental and physical health. And the second objective of this study was to identify the factors that promote effectiveness for women health. The first objective of this study was to identify the effectiveness of primary care interventions aimed at improving women's mental and physical health. And the first objective of this study was to identify the factors that promote effectiveness for women health. So to do this systematic review, we selected five academic databases. PubMed, BMC Medicine, Medline, Sinha and the Koran Library as our data source. The inclusion criteria for this study was that we added only those studies conducted on Pakistani women of above 18 years of age. And they delivered the intervention in primary health care sector, not in the secondary health care sector or in the tertiary health care sector, i.e. the basic health unit level that the intervention was delivered. If we talk about the comparator, we included those studies in which our control group or comparison group was added. And we saw the studies in which the outcome was mental or physical health in nature. And we only selected those studies which were the randomized control trials or quasi-experimental design with the control group. So in our initial search from the databases, we selected 135,553 academic papers in which 505 were the duplicates. And after removing those duplicates, the number of the research studies was 109,841. Through initial screening, we found that 109,298 studies were not related to the Pakistan. And we excluded those studies from our systematic review. And after excluding those studies, we only had 543 studies for our analysis. And after selecting these 543, we did abstract screening and 443 studies were selected on the basis of abstract screening. And by following the procedure inclusion and exclusion criteria, we selected 100 studies for our analysis. And out of those 100 studies, we only selected 18 studies for the descriptive analysis. And after reviewing those 18 studies, we developed our narrative synthesis. So this example was to show the process of the systematic literature review when we conduct the systematic literature review. What kind of procedures we had to follow for conducting systematic literature review.
