Treatment of UI after radical: electric or magnetic energy vs no treatment

Number of incontinent men ‐ after 12 months · Patients with postprostatectomy UI

Treatment of UI after radical: electric or magnetic energy probably leads to lower number of incontinent men ‐ after 12 months compared with no treatment (moderate certainty).

Dietary supplements (hypericum perforatum / St John's Wort) vs placebo

Relief of burning/discomfort (symptom relief; pain intensity) · People with primary burning mouth syndrome (BMS), that is, oral mucosal pain with no dental or medical cause for such symptoms
1 finding from 1 review

Electrical conductance (e.g. electronic caries monitor, ECM) vs Reference standard: histology or enhanced visual-tactile examination

Outcome not reported · Adults presenting asymptomatically or suspected of having root caries (in vivo); extracted teeth of adults (in vitro)

The review found no eligible studies for this question.
