===== Study aim ======


📚 Study Aim (Definition):

The **study aim** is the **main objective or purpose** that the researchers want to achieve with their study.  
It explains **what** the study is trying to find out, prove, analyze, or describe — in a simple and focused way.

✅ It answers the question:  
**"Why is this study being done?"**

 🔍 Characteristics of a Good Study Aim:
- **Clear** → easy to understand.
- **Focused** → not too broad.
- **Relevant** → connected to an important scientific or [[clinical question]].
- **Specific** → avoids vague or general terms.

🩺 Example (based on your topic):

- **Good Study Aim:**  
> "To assess the deviation between the preoperatively planned and the final position of pedicle screws inserted using navigation or robotic systems."

- **Bad Study Aim:**  
> "To study pedicle screws and surgery."  
(Too broad, not focused.)

In **quality assessments** like MINORS, they ask if the study has a **clearly stated aim** because a poor or unclear aim usually predicts poor overall study quality.
