```I have to interpret the effect of gender on blood
flow.
I have copied the result from stata.

Source |       SS       df       MS
Number of obs =      79
-------------+------------------------------
F(  1,    77) =    5.34
Model |  52.8286516     1  52.8286516
Prob > F      =  0.0235
Residual |   761.23203    77  9.88613026
R-squared     =  0.0649
-------------+------------------------------
Total |  814.060681    78  10.4366754
Root MSE      =  3.1442

------------------------------------------------------------------------------
mfm1 |      Coef.   Std. Err.      t    P>|t|
[95% Conf. Interval]
-------------+----------------------------------------------------------------
gender |  -1.674738   .7244781    -2.31   0.023
-3.117358   -.2321178
_cons |   9.453125   .4538293    20.83   0.000
8.549435    10.35681
------------------------------------------------------------------------------

How do I interpret which sex (gender) ?Male or ?Female
is explains the decrease in blood flow. Gender
accounts for 6% of variability in blood flow.
