a randomised double trial was conducted on use of suture x and y for episiotomies, with addition of anti inflamatory/ placebo. the outcome was measured by need of anal gesics.
suture x 60 .7%
suture y -54.4%
1 .the supirioty of suture y over x is statistically significant
2.comparing suture x with y if p=0.4 then obs could have occured by chance on 4 out of 1000 [ this should be 40 out of 1000 am i getting the math right or not]]
1-true
2-false
is the value of p should be <0.05 for any test to be statistically significant
