That looks like an asymmetric error bar, meaning the best estimate is 6.2 but could be 2.2 above or 1.3 below.
Essentially it's a common physical scientist way of expressing a point estimate with a confidence interval. (In the life and social sciences they tend to just provide the point estimate and confidence interval explicitly.)
