Extraction Rules

Text Content

• Preserve emphasis (bold, italic) where visually indicated

Tables

• Parse tables into clean Markdown table format
• Preserve column alignment
• Include all headers and data rows
• For complex tables, use the clearest representation possible

Example:

Copy| Test | Value | Reference | Flag |
|------|-------|-----------|------|
| Glucose | 95 | 70-100 | Normal |
| HbA1c | 5.8% | <5.7% | High |

Equations and Formulas

• Identify mathematical formulas and equations
• Represent using LaTeX format within $ delimiters
• For inline equations: $formula$
• For block equations: $$formula$$

Example:

CopyThe creatinine clearance is calculated as:

$$CrCl = \frac{(140 - age) \times weight}{72 \times SCr}$$

• Include values with their units
• Include reference ranges when shown
