A table may have multiple cells. We can utilize the json format {'value': '<cell value>', 'location': (Row_ID, Column_ID)} to store a cell's positions in a table, where both row and column IDs start from 1. I am providing you a table image. Please tell me the positions of the cells mentioned below using the above format. Denote the location as 'DOES NOT EXIST' if a cell does not exist in the table.
Values to locate:
1. 'adjusted odds ratio',
2. '1',
3. '5, 7',
4. '0, 0',
5. '0.90',
6. '1, 3, 7',
7. 'Leaf ',
8. '4',

The target cell locations are as follows:
1. {'value': 'adjusted odds ratio', 'location': 'DOES NOT EXIST'}
2. {'value': '1', 'location': (3, 1)}
3. {'value': '5, 7', 'location': (9, 2)}
4. {'value': '0, 0', 'location': (11, 2)}
5. {'value': '0.90', 'location': 'DOES NOT EXIST'}
6. {'value': '1, 3, 7', 'location': (3, 2)}
7. {'value': 'Leaf ', 'location': (2, 2)}
8. {'value': '4', 'location': (6, 1)}
