One percent is not statistically significant. They don’t know this?
Here’s an excerpt from another idea to give everybody an idea of why this is significant:
With 4 million hospitalized patients receiving fluids annually nationwide, one in a hundred starts to add up, co-author and ER physician Wesley Self says in a statement.
The study’s authors estimate that more than 50,000 deaths could be avoided with the change and twice as many cases of renal failure. Even just at Vanderbilt, they estimate the switch almost exclusively to balanced fluids could save hundreds of lives a year.
If the sample size is large enough, 1% can actually be a statistically significant result.
