Table 6 Absolute and relative risk by indication and overall (pooled datasets)

From: Suicidality and divalproex sodium: analysis of controlled studies in multiple indications

  Placebo DVPX Relative risk Risk difference per 1,000 subjects
  n/N Absolute risk per 1,000 subjects n/N Absolute risk per 1,000 subjects Incidence of events in DVPX subjects/incidence in placebo subjects Additional DVPX subjects with events
Placebo-controlled and low-dose-controlled studies
Indication:       
Epilepsy 1/204 4.90 1/208 4.81 0.98 -0.09
Psychiatric 9/726 12.40 10/926 10.80 0.87 -1.60

Placebo-controlled studies
Total 9/992 9.07 11/1,137 8.29 0.91 -0.78
  1. DVPX = divalproex sodium; n = number of subjects with events across studies; N = number of subjects treated across studies; - = relative risk cannot be calculated due to zero events in studies.
