- Reports (a)
- Observed count of this preferred term for the brand through the month (cumulative).
- E (MGPS)
- Age/sex-stratified expected count under MGPS (Mantel–Haenszel).
- E (RGPS)
- Regression-adjusted expected count under RGPS (accounts for product masking).
- PRR
- Proportional Reporting Ratio — unstratified [a/(a+b)] / [c/(c+d)].
- EBGM
- MGPS score: Empirical Bayes Geometric Mean of a / E(MGPS) after shrinkage.
- EB05
- 5th percentile of the MGPS posterior (lower credible bound for EBGM).
- ERAM
- RGPS score: Empirical Bayes Arithmetic Mean of a / E(RGPS) after shrinkage.
- ER05
- 5th percentile of the RGPS posterior (lower credible bound for ERAM).
- Masking
- How much RGPS raises the score over MGPS: ERAM/EBGM − 1 (shown as %).
- Predictors
- Number of other vaccine products selected as RGPS masking predictors for this PT.
