Recently, I released Odds Ratio–based suggestions and reports, such as the example shown here.
The underlying concepts are straightforward:
- If you are in an unhealthy range, the goal is to move out of that range.
- If you are not in an unhealthy range but fall outside a defined healthy range, the goal is to move into the healthy range.
For healthy ranges, interpretation is simple—you are either too high or too low, so the direction of adjustment is clear.
- If the range is 10%ile to 30 %ile and you are at 29%ile, should you increase or decrease?
- If the range is 70%ile to 90 %ile and you are at 85%ile, should you increase or decrease?
Unhealthy ranges, however, are more nuanced.
For example:
- If the unhealthy range is the 10th to 30th percentile and your value is at the 29th percentile, should you increase or decrease?
- If the unhealthy range is the 70th to 90th percentile and your value is at the 85th percentile, should you increase or decrease?
The core issue is understanding why the range is considered unhealthy—specifically, whether the problem arises from having too little of something or too much.
- Lactobacillus delbrueckii
- Unhealthy: 0 – 45%ile
- Healthy: 48%- 72%ile
- Lactobacillus gasseri (A Surprise!): 0 -100%ile is Unhealthy
- Lactobacillus johnsonii: 0 – 72%ile Healthy
- Lactobacillus taiwanensis: 23-56%ile Unhealthy
- Limosilactobacillus reuteri: 0-52%ile Unhealthy
The above numbers are slightly suspect because many are P > 0.002, so may not be significant.
| Confidence | Bacteria this or less significant | Bacteria More Significant |
| P < 0.001 | 2081 Ranges | 694 Ranges |
| P < 0.0001 | 2383 Ranges | 392 Ranges |
| P < 0.00001 | 2495 | 280 |
A List of Families with high significance
It is interesting to note that neither Lactobacillaceae (Lactobacillus) nor Bifidobacteriaceae (Bifidobacterium) were found to be significant at this level. Nor were they at the genus level, only at the specific species level (see below)

Summary
I am hoping to expand the size of my “Healthy Samples” in the next weeks. This should improve the ranges and significance.
