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
-------------+------------------------------          
Adj R-squared =  0.0528
       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. 
Please advice.
