Table 1 Summary of recurrences, p value (log-rank) and hazard ratio (HR) values (Cox PH) for 18 trial centers

From: Quality of transurethral resection of bladder tumor procedure influenced a phase III trial comparing the effect of KLH and mitomycin C

  1. Hospitals with p < 0.05 highlighted in gray
  2. *HR value larger than 2.26 (over all HR value based on all 18 hospitals)
  3. **HR value not available since no recurrences in the mitomycin C group
  4. KLH Keyhole Limpet Hemocyanin, MM mitomycin C, TURBT transurethral resection of bladder tumor
