In contrast, most control group patients had pH below 5 indicating that acidity correlates with low frequencies of atrophy 10%. Over 10 years ago a study by El-Omar and colleagues with a design to that of this study evaluated gastric pH with a more complex and more expensive method 33.
En contraste la mayoría de los pacientes del grupo control tuvieron un pH <5, lo que significó que la acidez en ellos estaba preservada; esto los "protege" o les disminuye el riesgo de CG 5, 9, 15.
