![]() ![]() First, presence of a positive OR for an outcome given a particular exposure does not necessarily indicate that this association is statistically significant. ![]() ![]() This example illustrates a few important points. Interestingly, the odds of persistent suicidal behaviour in this group given presence of borderline personality disorder at baseline was twice that of depression (OR 3.8, 95% CI:1.6–8.7), and was statistically significant (p 0.002) In fact, this is indicated in Table 1 of the reference article, which shows a p value of 0.07. Since the 95% CI of 0.96 to 2.80 spans 1.0, the increased odds (OR 1.63) of persistent suicidal behaviour among adolescents with depression at baseline does not reach statistical significance. ![]()
