Also, this study found that ST eradication efficacy was less than that found internationally. Data collected in 22 clinical trials including 2,388 patients demonstrated an average 91.3% eradication rate by intention to treat 95% CI:.90.2 to 92.5 and a 93.7% average eradication rate by protocol 95% CI: 92.7 to 94.7%, In comparison our study found a 62% eradication rate by intention to treat 95% CI: 51 to 72 and a 75% eradication rate by protocol 95% CI: 63 to 85. The rates found in our study were also lower than those found in Spain of 84% by intention to treat and 90% by protocol 26.
De igual manera, la TS en el presente trabajo tuvo una eficacia inferior a la encontrada a nivel internacional cuyos datos agrupados de 22 ensayos clínicos con 2.388 pacientes dieron tasas de erradicación por intención de tratar de 91,3% IC 95% 90,2-92,5 y por protocolo de 93,7% IC 95% 92,7-94,7%, versus 62% IC 95% 51-72% y 75% IC 95% 63-85% respectivamente, e igualmente por debajo de lo encontrado en España 26 que por intención de tratar el éxito fue de 84% y por protocolo de 90%.
