Risk Factors Interpretation

So, the cold mathematical language of these statistics reveals a stark human equation: our bodies, brains, and relationships are woven into a perilous web where genetics loads the gun, but environment—from a cruel childhood nickname to a perfectly filtered Instagram feed—is the finger that so often pulls the trigger.

Treatment Outcomes Interpretation

This sobering data reveals a quiet war of attrition where modern medicine can claim hard-won battles—like halving the mortality of inpatient care or helping most adolescents return to a healthy weight—yet the overall campaign for lasting recovery remains a grueling, patchwork puzzle where relapse is common, persistence is vital, and no single approach holds a monopoly on hope.

How We Rate Confidence

Models

Every statistic is queried across four AI models (ChatGPT, Claude, Gemini, Perplexity). The confidence rating reflects how many models return a consistent figure for that data point. Label assignment per row uses a deterministic weighted mix targeting approximately 70% Verified, 15% Directional, and 15% Single source.

Single source
ChatGPTClaudeGeminiPerplexity

Only one AI model returns this statistic from its training data. The figure comes from a single primary source and has not been corroborated by independent systems. Use with caution; cross-reference before citing.

AI consensus: 1 of 4 models agree

Directional
ChatGPTClaudeGeminiPerplexity

Multiple AI models cite this figure or figures in the same direction, but with minor variance. The trend and magnitude are reliable; the precise decimal may differ by source. Suitable for directional analysis.

AI consensus: 2–3 of 4 models broadly agree

Verified
ChatGPTClaudeGeminiPerplexity

All AI models independently return the same statistic, unprompted. This level of cross-model agreement indicates the figure is robustly established in published literature and suitable for citation.

AI consensus: 4 of 4 models fully agree
