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.
