I don't understand how the test was performed, this was available in literature and so I was referring to the same.

I require assistance for a study hypothesis and statistical analysis plan for the below. (1) Research question : To find time to stop bleeding with use of product. (2) Data Collection : Time take to stop bleeding will be captured with use of a stop watch. Eg. Patient 1= 5 minutes; Patient 2 =...

Thanks for your inputs. If t test is similar to Confidence Interval, I will just go ahead with confidence interval. Also is it possible to find confidence interval for below outcome. Patient comfort levels as assessed by verbal inquiry: Excellent - 59 patients Good - 11 patients Fair - 0...

Noted with thanks. I require assistance with another study as well. Please let me know if you can help. I will write in another post.

The hypothesis is time to stop bleeding is greater than 10 minutes. Is there a way to find the effect size ?

Thanks for your valuable inputs. How do I perform a t test and get a p value to reject the null hypothesis. I was referring to that attached reference. Attached reference has ambulation time. and has a p value of <0.0001 to reject the null hypothesis. In my case I am trying to check similar...

Research Question: How much time does it take to stop bleeding (Haemostasis) after transracial catheterisation. Study product: Chitosan dressing used to stop bleeding from puncture site Method : Chitosan dressing was applied on the puncture site to stop bleeding. Sample Size: 70 I have data...

My sample size is 70. I have a series of values for time to haemostasis. I do not have pre and post data. The samples is analysed as mean and standard deviation. Let me know if more information is required.

What is effect size and how to calculate for a single group study?

Apologies for the confusion. I am sharing a reference study, I am trying to run my study in a similar way. Can you help to know what data was collected and how analysis is performed for the attached reference study.

I have used attached reference for my study. If you can, please help to know how analysis was performed, I can perform my analysis accordingly. Thanks in advance!

I am sharing the calculation. Treatment 1 = TTH for all 70 samples Treatment 2 = TTH - 10 for all 70 samples.

Null Hypothesis : Mean of Intra-subject Time to Haemostasis (TTH) = > 10 min Alternate Hypothesis : Mean of Intra-subject Time to Haemostasis (TTH) </= 10 min Sample Size : = 70 I have TTH values for all the 70 samples as performed during the study. I calculated values for (TTH - 10) for all...

This is for sample size calculation.
