Re: Hazard ratio, P value, what the.....
the value P tells researchers if the differences they found are statistically significant. w/o reading the entire article...it looks as if it is saying that there is a statistically significant difference in the hazard ratio between participants who used condoms more than 65% of the time and those that did not.
researchers evaluate differences between groups of participants in terms of statistical significance. they perform statistical analyses and the specific tests helps establish what is cinsidered significant. in all research there are always differences between groups, but the analyses determine if the differences are coincidental or if there's a relationship. if the difference "passes" the test for significance, then we know that there is a relationship, in this case, between condom use >65% and the risk ratio.
if you read a study and dont understand the statistical analysis, skip to the discussion and conclusion sections. the results are usually very technical and require some experimental statistics background.
if you're still interested and have a link to the article, i could read it (and actually would like to...hence the reply to an older post).
