What did you say the error was??

I was looking at some experimental data for drug molecules binding to a pharmaceutically relevant protein.

The numbers reported were as percentages of binding relative to a standard which was defined to be 100%. Here's how they looked:

97.3 + - (plus or minus) 68.4
79.4 + - 96.1
59.5 + - 55.3
1.4 + - 2.5

Seriously, how did the reviewers allow this to go through?
