Evidence Calibration

Grade A

Bayesian back-testing of convergence scores against known drug outcomes — the critical self-check that separates rigorous research from speculation. For each drug with a known clinical outcome, the platform asks: did our evidence scoring predict the right outcome?

How does Calibration Process work?

(1) Outcome collection— gather real-world drug approval/failure data from ClinicalTrials.gov and FDA records. (2) Score comparison— compare each drug’s convergence score against its actual clinical outcome. Approved drugs (nusinersen, risdiplam, onasemnogene) should score high; failed drugs should score low. (3) Bayesian updating— compute posterior probabilities measuring how well evidence mass predicts clinical success. (4) Grade assignment— A (well calibrated) to F (poorly calibrated).

A well-calibrated platform means researchers can trust the convergence scores when evaluating novel, untested targets.

Calibration Curve

Each bin groups drugs by their convergence score. The green line shows actual clinical success rate within that bin. The dashed line is perfect calibration (predicted = actual). Bins with n=0 have no scored outcomes.

Calibration Metrics

Separation Score
How well convergence scores separate successful vs failed drugs. Higher = better discrimination.
0.7319
Rank Correlation
Spearman correlation between convergence rank and clinical outcome. >0.3 is meaningful.
100.0%
Prediction Accuracy
Fraction of drugs where convergence score correctly predicted success/failure.
0.1371
Brier Score
Mean squared prediction error. 0 = perfect, 0.25 = random chance. Lower is better.
202
Outcomes Tested
Total drugs with known clinical outcomes used for calibration. More = more reliable.
141
With Convergence
Drugs that have both a clinical outcome AND a computed convergence score.
Baseline comparison: Random classifier ~0.25, our 0.1371 is 45% better than random. Sample size 202 (141 scored). Larger samples increase confidence in calibration results.

Uncertainty Quantification

Wilson score confidence intervals on target support ratios. Grade A = narrow CI (high certainty), D = wide CI (needs more evidence). CI width reflects evidence volume, source diversity, and claim consistency per target.
