A study looks at 100 dogs that walk daily (DWD) and 100 dogs that walk weekly (DWW) and follows them for development of cracked toe beans. At the end of the study, they found that 30 of the DWD and 10 of the DWW developed cracked toe beans. Draw a 2x2 table and find the OR and RR.

Fill in the blanks

(0/0)

The OR (2dp) =

The RR (2dp) =

The OR indicates to us that the odds that dogs that walk

are

times more likely to develop cracked toe beans than dogs that walk

The RR indicates to us that dogs that walk

are

times

at risk of developing cracked toe beans than dogs that walk

A study looks at 200 puppies born with short legs for their size and 150 puppies born with average sized legs for their size, and follows them for development of short legs within 6 months. At the end of the study, they found that 40 of the puppies born with short legs and 3 of the puppies born with average legs had short legs for their size after 6 months. Draw a 2x2 table and calculate the OR and RR.

Fill in the blanks

OR (2dp) =

RR (2dp) =

The OR indicates that the odds that puppies born with

legs for their size will have short legs after 6 months are

times

likely than puppies born with

legs for their size.

The RR indicates that puppies that are born with

legs for their size are

times more at risk of having short legs for their size 6 months later than puppies born with

legs for their size.

A study looks at 400 puppies with white fur and 200 puppies without white fur, and follows them for development of pink toe beans. At the end of the study, they found that 150 of the puppies with white fur and 5 of the puppies without white fur developed pink toe beans. Draw a 2x2 table and calculate the OR and RR.

Fill in the blanks

OR (2dp) =

RR (2dp) =

12.7

The OR indicates that the odds that puppies

white fur will develop pink toe beans is

times

likely than puppies

The RR tells us that puppies

white fur are

times

at risk of developing pink toe beans than dogs

white fur.
