Question

Dear Chegg Expert,

I am trying to interpret the above chart and would like it if you could pick one category and explain it through the chart. I do not know what (events, n) means or where they get that number. I am not sure if I can actually figure out the numbers or if they are just there for me to interpret. I would be grateful for any or all of the help you can give me. If it is not too much work, it would be acceptionally helpful to compare more than one category.

Thanks in advance,

Shani

Explanation / Answer

The above chart shows the risk ratios and confidence intervals of CRC which is COLORECTAL CANCER RISK associated with Green tea consumption .

This data extracted from the Shanghai's Women Health Study from the year 1996 to 2004.

Similarly the further categories are explained through the table .

Hope this helps.
