1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

mRNA vaccines can encode multiple tumor antigens whose presentation ultimately depends on adequate intracellular processing. To evaluate the potential impact of epitope-flanking sequences, we compared the immunogenicity of two mRNA vaccines in the MC38 mouse model. Both vaccines coded for the same tumor-specific antigens (TSAs). The only difference between the two vaccines was the identity of the epitope-flanking amino acids. The vaccine encoding TSAs bordered by optimized flanking sequences (TSA-Opti) cleared established tumors and elicited robust CD8
