For example, in one recent prospective case-control study, blood samples from 93 fasting people who had been diagnosed with CRC were assessed for levels of gastrin antibodies, antibodies against H. pylori and expression of the CagA protein by H. pylori. They were then compared with 20 age-matched controls 31.
Por ejemplo, en un reciente estudio prospectivo de casos y controles se tomaron muestras de sangre en ayunas de 93 personas diagnosticadas con CCR para evaluar el nivel de gastrina, anticuerpos contra H. pylori y la expresión de proteína CagA por H. pylori, y se compararon con 20 controles apareados por edad 31.
