Thx for easy Explaination. Could you please try to demonstraight the same in case of Crossover study with 3 period 3 treatments? In one of Crossover study i have observed that ADAM has 2 variales for TEAE. 1. TRTMFL (label-Treatment Emergent Analysis Flag) 2. AETRTMFL (label-Treatment Emergent Flag) At some instances responses are not match with eachother for these 2 flags. Could you explain why it so far? is there any difference in methodology behind these 2 mentioned flags?
Hi Sham, glad that you found this helpful. The best source for understanding your query is to check the requirement in the statistical analysis plan, if you have access to. I will try to create a video to explain treatment emergent flag derivation in cross over trials in general.
In some protocols, all the events that occur from the informed consent are collected as part of AE.. so, there will be some events between informed consent start date and treatment start date...
Adverse event is defined as 'Any untoward medical occurrence in a patient or clinical investigation subject administered a pharmaceutical product and which does not necessarily have a causal relationship with this treatment'. SDTM defines clinical events as any event of interest that would not be classified as an adverse event. For example, episodes of symptoms of the disease under study - episode of migraine in a study treating migraine, episode of a seizure in an epilepsy study, episode of hypoglycemia in a study treating diabetes, occurrence of stroke in a study providing preventive treatment for stroke. Subject experiencing unusual physical activity or stressful event because of wearing a device in study evaluating a new wearable device. All of these events provided in the above example on any other study would have been called adverse events. But, as the study design expects these 'events', they are called 'clinical events'.
Wonderful explanation 👍
Glad you found it helpful, Trupti. Thank you.
Thank you for information
You are welcome. Happy to help.
Hi sir, nice explanation 👍
Glad you liked the approach...

Thx for concern.
an event couldn't be present as adverse event before treatment getting started, then how it worsen after the treatment

Hii bro
Can you please explain difference between AE and CE

Thank you bro,
This is really helpful..
Glad that you found it helpful. Happy to help.
one condition is missing. AESTDT >= TRSTDT
Hi Ajay, on line 4 of the code which is creating ae04 dataset, we have the condition 'astdt ge trtsdt'. Are you referring to something else?
Superb sir
Glad that you found it helpful.
