do we have enough bandwidth in Ethiopia for people to turn their cameras on? we sometimes have problems with tz.

Yes, we have.

several questions: 1. is incidence per 100 child-weeks the usual measure in this field? some of us would prefer to think about per year. 2. is there a rainy season where sodis is not practical? what do you recommend at those times? 3. what is the price of bottles, compared to local income? would subsidization help? 4. was the trial only 12 weeks long? are there seasonal issues (e.g. diarrhea seasonality)? did your study period cover different seasons?

did you look for effect modifiers in a formal way?

nice study.

Thanks a lot!

Thankyou!
