User clicks "Semaglutide". This is the core view. It splits reality into three layers.

FDA Label (2023-01): "GI adverse events common. No mention of paralysis."

[ LAYER 2: THE LATENT SIGNAL (Tier 4-5) ]
|
|
────────────────────────────────────────────────────────────────────────
|
|
Reddit (/r/Ozempic): "Stomach paralysis" (Cluster: 412 posts, +45% WoW)
|
|
Twitter (MDs): "Seeing ER admits for aspiration pneumonia." (12 sigs)
|
|
FAERS (Raw): "Gastric obstruction" (84 unverified reports)
|
|
────────────────────────────────────────────────────────────────────────
|
|
|
|
[ ANALYSIS: THE SKEPTIC LENS ]
|
|
"The Official Truth says GI issues are 'Transient'.
|
|
The Latent Signal says GI issues are 'Permanent/Severe' (Paralysis).
|
|
|
|
This is a CATEGORICAL CONFLICT.
|
|
Signal Authority: Low (Tier 5) but Density is High (Vol > 400)."

[ INSIGHT ]
|

The Latent Signal emerged in 2023-Q2. The Label is lagging by ~6 months.
|
|
Predicted Label Update: Q4 2023 (Probability: 75%)

[ KEY EXCERPTS ]

1. "ER Doc said my stomach essentially stopped working. Been off Oz for 3mo."

2. "Diagnosed with gastroparesis after 6 months on 1mg."

|
|
|
|
[ RELATED CLINICAL CONTEXT ]
|
|
* Does this match Mechanism of Action? YES (GLP-1 slows gastric emptying).
|
|
* Is it in the Label? NO (Label says "nausea", not "paralysis").

## 5. The Command Line (The "Power User")
|
|
|
|
For the analyst who wants to query the graph directly.

|
|
|
```text

|
|
|
|
[RESULT]
|
|
Subject: Semaglutide
|
|
Predicate: side_effect
|
|
|
|
1. Nausea (Confidence: 0.99) [Consensus]
|
|
- Sources: FDA, EMA, NEJM, Reddit
|
|
|
|
2. Vomiting (Confidence: 0.98) [Consensus]
|
|
- Sources: FDA, EMA, Reddit
|
|
|
|
3. Gastroparesis (Confidence: 0.45) [CONFLICT]
|
|
- Sources: Reddit (High Vol), Twitter (Med Vol)
|
|
- Contradicted By: NEJM ("No signal")
|
|
- Source Tier Spread: 4 (Tier 1 vs Tier 5)
|
|
|
|
> latent simulate --event "FDA Warning Added"
|
|
|
|
[SIMULATION]
|
|
If FDA adds "Gastroparesis" warning (Tier 0):
|
|
- Conflict Score drops to 0.1 (Resolution reached).
|
|
- Liability risk for past prescriptions increases (Knowledge date: 2023-Q2).
