Solving for the correlational value

This paragraph is from an article I am studying. I am suppose to know how to generate and explain a correlational value by this data.

During the 10-month period during which these six exposures were detected, a total of 2,316 general anesthetics using isoflurane or desflurane were delivered in operating rooms monitored by mass spectrometry. All cases of carbon monoxide exposure occurred with isoflurane anesthesia during the first general anesthetic of the day in that particular operating room, and the corresponding number of
first cases was 1,372. This results in an incidence of 6 of 2,316 or 0.26%, but for first cases, the incidence of carbon monoxide exposure from anesthetic breakdown was 6 of 1,372 or 0.44%.

All regression lines are statistically different from each other, and all have r2 values > 0.95.

The article also gave the value m/z = 69, and r2>0.95.

I am thankful for whatever information you can provide.

The correlation coefficient is r and r^2 is the coefficient of determination.
The following statement indicates that "Although these inappropriately indicated quantities of "enflurane" correlated (r2 > 0.95) ...
