degree of collagen fiber reduction

En fait j'aurais dû ajouter "absent", ce que je ne comprends pas c'est la structure de la phrase "The degree of collagen fiber reduction and inflammatory infiltration were absent" : en français, on ne dirait pas "l'absence du degré de réduction"... ?

Voici le paragraphe en entier :

Student's t-test was used for statistical analysis of the mean number of fibroblasts before and following tamoxifen treatment ( P < 0.05). The degree of collagen fiber reduction and inflammatory infiltration were absent before treatment and present in 100% of cases after treatment, while the mean number of fibroblasts was significantly lower after intralesional tamoxifen treatment ( P < 0.0001).
