The odds ratio calculator will output: odds ratio, two-sided confidence interval, left-sided and right-sided confidence interval, one-sided p-value and z-score. If the test was two-sided, you need to multiple the p-value by 2 to get the two-sided p-value. Odds Ratio (OR) can be calculated manually by creating 2*2 contingency table. However, For p-value and CIs it is customary from SPSS or Epi-Info or more advanced software. Relative Risk and Odds Ratio Calculator. This Relative Risk and Odds Ratio calculator allows you to determine the comparative risk of the occurrence of a significant event (or outcome) for two groups. For example, suppose the members of one group each eat a kilo of cheese every day, and the members of another group eat no cheese, and you have data for both groups on the incidence of heart Instructions: This calculator computes the Odds Ratio (OR) for a 2x2 crosstabulation, which measures the ratio of the odds of exhibiting a condition (or disease) for those in an exposed group, versus the the odds of exhibiting the condition (or disease) for those in the non-exposed group. Please type the 2x2 table data and also indicate the confidence level required to compute the confidence P-value from Z score. P-value from t score. P-value from chi-square score. P-value from F-ratio score. P-value from Pearson (r) score. P-value from Tukey q (studentized range distribution) score. Critical Values Calculators. Critical values calculator. Tukey q calculator. Note: If you require the full statistical test calculators, then you P value calculator. Calculate the p-value for the following distributions: Normal distribution, T distribution, Chi-Square distribution and F distribution. The odds ratio is 0.7037 and log(OR) is -0.3514. For a contingency table with values a, b, c, and d, the variance of log(OR) is given by (1/a + 1/b + 1/c + 1/d) How can I calculate the p.value of log(OR) from this data in R (whether it is significantly different from 0)? P-value Calculator This online statistical tool calculates left-tailed and right-tailed P-values from various test scores (z-score, chi-square, Student’s t-value). Choose the type of the statistics distribution and enter the input data in the appropriate fields of this P-value Calculator to get the corresponding P-value. Usage Note 53376: Computing p-values for odds ratios PROC LOGISTIC automatically provides a table of odds ratio estimates for predictors not involved in interactions or nested effects . A similar table is produced when you specify the CLODDS=WALD option in the MODEL statement. MedCalc's free online Odds Ratio (OR) statistical calculator calculates Odds Ratio with 95% Confidence Interval from a 2x2 table.
