    Study Conclusions

    Conclusions
    3177 cases in 2.5 yearIn Japanese men with AGA, long-term treatment with finasteride 1 mg tablets maintained high efficacy without recognized side-effect.
    801 cases in 5 yearYounger age and less advanced disease at start of treatment were the key predictors of higher finasteride eficacy.
    Finasteride has lower efficacy in patients over 40 years old and in patients with advanced N-H scale (over N-H: IV) at the first visit.
    532 cases in 10 yearLong-term(10-year)AGAtreatmentwithfinasteride1mg/daydemonstratedahighefficacyandsafety based on subjective and objective evaluations in Japanese men.
    The group with N-H:I/II/III at the first visit showed greater improvement than the group with N-H: IV/V/ VI/VII at first visit, following 10 years of AGA treatment with finasteride.
