hazard ratio definition
Hey there,
Just another stats question regarding hazard ratios (HR)...so say I have 4 groups of people who drink varying amounts of cups of tea a day with regard to diabetes type 2.
01 cups,
1.12 cups,
2.13 cups,
3.15 cups
>5 cups
and then they work out the HR after adjusting for a number of factors such as BMI, smoking, age etc and say the HR for those in the 1.12cups/day if 0.77 and in the >5.0 the HR is 0.71 is this the way I would interpret it?
In those who drink 1.12 cups of tea a day they have a 23% less chance of developing type 2 diabetes than say someone in the other groups but seeing as the HR for the >5 cups is 0.71 this group have a 29% less chance of developing T2Diabetes?? Hence the >5 are the LEAST LIKELY to develop T2Diabetes??
Have I understood this correctly?
Helllp :S

what about the other groups? Do they have bigger or smaller change to get the diabetes?
Also, I think, that it matters, whether you drink the tea with or without sugar. E.g. I'm drinking tea with lot of sugar, so if I drunk 5 cups, I would get like 1 pound of suger per day

Cis or trans? That's what matters.

Re: hazard ratio definition
Hi there,
the HR for all groups are:
01 cups (reference group)
1.12 cups HR=0.77
2.13 cups HR=0.93
3.15 cups HR=0.78
>5 cups HR=0.71
so in this case it means that you are 29% less likely to get T2D compared to the other groups if you drink more then 5cups/day right?....is this correct...
good point about the sugar..=)
