Design outcomes

Primary

Measure	Time frame
In this study, we mainly target a group that includes a large number of healthy individuals undergoing medical check-ups, and aim to clarify the characteristics of the gastrointestinal microbiota of the so-called general population in Japan by analyzing the bacterial flora in saliva and feces.	—

Secondary

Measure	Time frame
This research primarily targets a population comprising mostly healthy individuals who undergo comprehensive health checkups, with the aim of analyzing the bacterial flora in saliva and feces to elucidate the characteristics of the gastrointestinal microbiota among the so-called general populace in Japan. Furthermore, by evaluating the current medical history and the condition of the oral cavity, including the tongue, this study seeks to clarify the relationship between the current medical history, the state of the oral cavity, and the gastrointestinal microbiota.	—
