Timing of TB recurrence and death for 111 multi-drug resistant tuberculosis patients evaluated four years after being successfully treated for TB in 2004.

cum. = cumulative.SS/C+ = Sputum smear or culture was positive at time of follow-up.Comparison of recurrence rate between new cases and retreatment cases: Pearson X2 = 4.481, P = 0.03.Comparison of SS/C+ TB recurrence rate between new cases and retreatment cases: Pearson X2 = 0.132, P = 0.72.Comparison of death rate between new cases and retreatment cases: Pearson X2 = 5.169, P = 0.02.Comparison of death due to TB between new cases and retreatment cases: Pearson X2 = 8.318, P = 0.003.

cum. 即累积（cumulative）。SS/C+ 指随访时痰涂片或培养阳性（Sputum smear or culture was positive at time of follow-up）。初治病例与复治病例的复发率比较：皮尔逊卡方（Pearson X2）= 4.481，P = 0.03。初治与复治病例中痰涂片或培养阳性（SS/C+）结核病患者的复发率比较：皮尔逊卡方（Pearson X2）= 0.132，P = 0.72。初治与复治病例的总死亡率比较：皮尔逊卡方（Pearson X2）= 5.169，P = 0.02。初治与复治病例的结核病相关死亡率比较：皮尔逊卡方（Pearson X2）= 8.318，P = 0.003。
