I read this paper, and at the end of page 841 there is this sentence:

demonstrating that state transitions exert a differential 
effect across the firing rate spectrum (slope, 95% confidence interval 0.66–0.71)

What really means the value 0.66–0.71? How it is obtained?
I couldn't find more detail in the article...

Thanks a lot

EDIT : Extract from the paper:

enter image description here (B) Differential effect of brain state on neurons of different firing rates. Comparison of the firing rates (log scale) of the same pyramidal neurons during WAKE and nonREM—each point is the same neuron in two states. During nonREM, neurons at the right end of the distribution are decreased, but neurons at the left end of the distribution increase their rates compared to WAKE (arrows).

  • $\begingroup$ @whuber : thanks for these links, but it remains unclear for what was done in this specific article. $\endgroup$ – Dadep Oct 9 at 13:04
  • $\begingroup$ I believe some of the links are explicit about the construction of the confidence intervals. This is such a standard procedure--the intervals often are automatically reported by least-squares regression software--that one can feel comfortable that the accounts in the duplicate answers describe what the paper's authors did. $\endgroup$ – whuber Oct 9 at 13:11
