2. Beta blocker is more effective in controlling essential tremor than no treatment.
3. Beta blocker is more effective in controlling essential tremor than other drugs for essential tremor .
4. One beta blocker is more effective in controlling essential tremor than another

5. A high dose is more effective in controlling essential tremor than low dose.
