The Trials Register of Promoting Health Interventions (TRoPHI)

About this database

The Trials Register of Promoting Health Interventions (TRoPHI) is unique in its focussed coverage of trials of interventions in health promotion and public health worldwide. It covers both randomised and non-randomised controlled trials and currently contains details of over 4,500 trials.

All reports of trials are assessed and systematically keyworded with generic keywords (e.g. country, health focus, population group, intervention characteristics (including setting, provider and type) and trial type (RCT or trial).

Recording your findings

To record results of your searches, you can print out your searches or reports, or cut and paste the table into word processing software. Landscape format provides the best results.

How are the reviews identified?

The reports are identified in the following ways:

  • As a result of searches to identify studies for systematic reviews within the EPPI-Centre;
  • Quarterly sensitive searches since August 2004;
  • As the official register of the former Cochrane Health Promotion and Public Health field, it contains the results of hand searching journals conducted by the Field.
How current is the register?

TRoPHI is updated quarterly to keep it as current as possible.
