Obese	Not obese	Total
SSB consumer	125	125	250
Non-SSB consumer	250	500	750
Total	375	625	1000

Genetic variant present:

	Obese	Not obese	Total
SSB consumer	85	25	110
Non-SSB consumer	150	250	400
Total	235	275	510

Genetic variant absent:

	Obese	Not obese	Total
SSB consumer	40	100	140
Non-SSB consumer	100	250	350
Total	140	350	490

4. Using the stratified tables above, calculate:
   1. Risk of obesity among those with the genetic variant who consume SSB (R_G+SSB+)

2. Risk of obesity among those with the genetic variant who do not consume SSB (R_G+SSB-)

3. Risk of obesity among those without the genetic variant who consume SSB (R_G-SSB+)

4. Risk of obesity among those without the genetic variant who do not consume SSB (R_G-SSB-)
