The title doesn't contain any conclusion.
>Vitamin D supplementation to prevent acute respiratory infections: systematic review and meta-analysis of stratified aggregate data
What with HN's 80 character limit something had to go!
I apologize for making it "misleading" but what would you have done?
Someone else quoted this as the results from the study:
> For the primary comparison of any vitamin D versus placebo, the intervention did not statistically significantly affect overall ARI risk (OR 0·94 [95% CI 0·88–1·00], p=0·057; 40 studies; 61 589 participants; I2=26·4%).
Are you suggesting that should be in the title? Would it even fit?
When I read the "Vitamin D supplementation to prevent" part, I got excited because I thought the research implied that supplementation does help. So I had to read it.
With the first title, I wouldn't read the study because I've read dozens of other studies showing how Vitamin D supplementation doesn't improve health outcomes.
