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
