I understood it as same as Anawat. In addition, I would like to suggest this site for self-learning. https://www.kdnuggets.com/2016/04/association-rules-apriori-algorithm-tutorial.html

I think this site provides content that is easy to understand. Hope it helps and pleases correct me if I misunderstood too!!

Since my objective for the HBV modeling from week 2 is to study HBV transmission dynamic only and I didn’t include any intervention in my model. However, I would like to slightly modify HBV focus and restructure the modeling, by focusing on “HBV infection received from mother-to-child route” in Thailand. The intervention is antiviral proph…[Read more]

I will use SIR model for the mathematical modeling of HBV transmission dynamic in Thailand regardless of vaccination and transmission route. The variables include S = susceptible, I = HBV infected, and R = recovered people (as suggested by https://science.buu.ac.th/ojs246/index.php/sci/article/view/1623/1551 ). Also, I is subclassified between…[Read more]

I am interested in using mathematical modeling to estimate hepatitis B disease in Thailand and probably the impact of the HBV vaccine. There are a few related articles:

There is one study using Thai data:…[Read more]

Thank you, Kansiri and Arwin 🙂

I love it!!. I am not actually a fan of a black background but you designed it well. It looks nice with the light text!!. The table and map/graph are well-designed and captured all necessary information. I have only one comment. I think the recovered/deaths data in the table represented cumulative numbers rather than daily cases (except, I select…[Read more]

The dashboard is informative and consists of several components/data. It would be nice for professionals such as public health specialists, data analysts, healthcare professionals, and statisticians. However, it might be a bot in-details for the general population.

Thank you, Arvin. That’s very helpful!!

Your CRF is comprehended and well-organized. I really like the brief informed consent part. However, I have a few questions and comments below.

– I am not sure whether we should separate the form for each visit or not – one for screening and one for enrollment. Therefore, this is still a doubt for me, and I can’t comment on any.
– I like the…[Read more]

I agree with you. It will allow easier data cleaning and can use these data for further analysis or collect in the big databases for other benefits/future research

A benefit of data standards for clinical research is all stakeholder can understand and interpret the data in the same way, structured data allows easier data cleaning, analysis and additional benefits in trials/big data.

Good point!!!. I found several questionnaires and other data collection forms providing choices only yes/no, negative/positive without “not applicable: option. The good point is it is mandatory for users to choose either choice but the disadvantage is like you mention. For someone who actually don’t know about that or no data, the section is…[Read more]

For weight and height, we can use box format with clear unit to prevent data entry error and easy to understand. However, the blank one is still acceptable (with written units)

Thank you for sharing. I heard about the program by Oracle before and it is quite well-known/commonly use in CRA, site monitoring. I have not used it myself but it seems similar to the PV system I used to collect the clinical/AEs data.

I don’t have any experience in clinical trial conducting but I did data collection in pharmacovigilance electronic database called ARISg system n my formal organization. There are audit trails, data backup and recovery plan in plan. All users will have specific account and every actions made would be collect on real-time basis and archive in the…[Read more]
