Raw impact of each value of additional stratifications on the baseline model of low-credibility amplification. The color yellow represents positive values, while blue represents negative values. Here, raw values imply that if in the base model a stratum had an amplification of +10%, and the addition of a third stratification pushed this to +12%, we would report this as a +2% difference, not +20%. In this sense, results here are a raw difference between percentages
