Table 2b. Numbers (%) of lung tumours showing loss at 2p16 according to asbestos-exposure level and extent of the lost DNA.
| Number of probesa showing loss at 2p16 | Highly expb (n=41) | Expc (n=29) | Non-expd (n=71) |
|---|---|---|---|
| 0 | 32 (78) | 24 (83) | 65 (91) |
| 1 | 5 (12) | 3 (10) | 4 (6) |
| 2 | 4 (10) | 1 (3.5) | 2 (3) |

Abbreviation: Exp=exposed.
a
Including the probes RP11-703K23, RP11-347F1, and RP11-1114A19.
b
Pulmonary fibre count ⩾5 million fibres per gram.
c
Pulmonary fibre count 1–<5 million fibres per gram.
d
Pulmonary fibre count ⩽0.5 million fibres per gram.
P=0.05, highly asbestos-exposed and asbestos-exposed vs non-exposed; P=0.04, highly asbestos-exposed vs non-exposed (P-values were calculated using χ2-test for the difference between at least one loss and no losses).
