I just pushed a new feature that is shown in the video below

The differences of the two methods are:

• Old method looks at the level of bacteria that you have only. This is ideal for making suggestions because we want to alter what is there.
• New, Odds Ratio method, looks at which bacteria were found (or missing) and their levels. Addressing missing bacteria is not trivial — unless it is a known probiotics species (99% are not)

Odds Ratio is likely more accurate because it considers what is there, the amount and what is missing. It is not an ideal choice for computing suggestions.

Remember Odds Ratios do not say you will have a symptom, it merely indicates increased odds of having the symptom.

Example below of two samples taken 5 years apart. Earlier sample, patient was 68, later sample 73. In general reflects well the symptoms reported.
