     1   MR. JUSTICE BELL:  I know, but we have to try to find it in the
     2        article.
     3
     4   THE WITNESS:  There is a little diagram which talks about fat
     5        intake percentage of energy, and there is less than 29 per
     6        cent up to greater than 49 per cent.
     7
     8   MR. JUSTICE BELL:  What are you looking at now?
     9        A.  Again on page 386 there is a little diagram to the
    10        right with confidence bars and talking of relative risks
    11        from the lowest which is less than 29 per cent of energy,
    12        to the greatest which is greater than 49 per cent of
    13        energy.
    14
    15   MR. MORRIS:  So does that mean that ----
    16        A.  What these relative risks show is that they all
    17        overlap each other irrespective.
    18
    19   MR. JUSTICE BELL:  Is there any particular pattern there at
    20        all?
    21        A.  No, none at all.
    22
    23   MR. MORRIS:  The point I am making is, for example, the
    24        population study which looks at a population where the
    25        average intake is 15 per cent or less of fat in the diet
    26        is more likely to show up if that would have an effect on
    27        causation of breast cancer.  All I am saying is there
    28        could be a threshold at which -----
    29        A.  There may be.
    30
    31   Q.   -- breast cancer is triggered in the amount of fat in the
    32        diet.  This survey would not show that, would it?
    33        A.  No, but when you are getting down to populations,
    34        where the intake of energy is less than 25 per cent from
    35        fat, one has to look at other aspects of their diet or
    36        other aspects of their lifestyle.  It is only the fact
    37        that they may derive 25 per cent of their calories from
    38        fat which is the agent which is directly related to the
    39        development of breast cancer or protective as far as
    40        breast cancer is concerned?.  It is not -- you cannot
    41        necessarily transpose the data.  It is a complex
    42        phenomenon.  This is the major problem.  It is a complex
    43        phenomenon.  There are other aspects of lifestyle which
    44        may be important as well as the fact that they only get 25
    45        per cent of their calories from fat.
    46
    47   Q.   Right.  If you look, coming to the next study I want to
    48        look at which is the China one.  I do not know whether the
    49        China one appears in the documents.  We did serve it at
    50        the end of the last session.  It was the one by Mr. Colin 
    51        Campbell.  If someone can help me to identify where that 
    52        might have been?  Colin Campbell's statement -- there are 
    53        two things.  There is his statement and his abstract from
    54        his actual report.  The statement seems to be in volume I
    55        blue, section H, tab 5, according to the plaintiffs'
    56        information that we have here.
    57        A.  Sorry, section?
    58
    59   Q.   That is what it says here.
