STATISTICAL ANALYSIS
All the data would be selected randomly and tabulated, and then analysed with appropriate statistical tools “Med Calc”. Data will be presented as mean with standard deviation or proportions as appropriate. Mean, median, standard deviation and variance would be calculated and following statistical significance tests would be applied. Abnormally distributed data were expressed as mean and standard deviation. Categorical variables were expressed as frequencies and percentage or relative values.
1. Statistical analysis would be done using “Chi – square Test” for categorical variables.
2. Odds Ratio (OR) with 95% class interval also calculated.
A “p-value” should be considered to be non-significant if > 0.05 and significant if <0.05.
Statistical methods would be used to find the significance of homogeneity of study characteristics between the two groups of patients. Their inference will be as follows-
P > 0.05 statistically insignificant
P < 0.05 statistically significant
P < 0.01 statistically highly significant
P < 0.001 statistically very highly significant
