A particular district of your nation had a higher incidence rate for polio last year compared to the rest of the country. That region has been traditionally been resistant to vaccination efforts. You have commissioned a case-control study for the village to evaluate the situation after a recent outbreak of the disease in the area to measure vaccination status among the 63 poliomyelitis cases and 126 age- and neighborhood-matched controls. Cases were found to be under-vaccinated through routine immunization (matched odds ratio [MOR], 0.3; 95% confidence interval [CI],0.10.5).a. What do the odds ratio and given confidence interval indicate? (3 points)The matched odds ratio 0.3 indicated that vaccination was associated with 70%decrease in the risk of poliomyelitis and the 95% confidence interval [0.1 0.5]indicated that we are 95% confident that vaccination was associated with [50% to90%] decrease in the risk of poliomyelitis. B. How was the odds ratio calculated? (3 points)There are 4 possible outcomes with respect to the matched pair: Case exposed; Control exposed Case exposed; Control not exposed Case not exposed; control exposed Case not exposed; control not exposed Let u is the number of pairs in which Case exposed; Control not exposed and v is the number of pairs in which Case not exposed; control exposed.Odds Ratio = u/v = 0.3

I need helpto elaborate on u and v inmy calculation; where would these fit on a 2x2 table?;I must explain thestatistics to an understandable level ina press release.
