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

Prime-boost regimens are frequently used to increase the number of memory CD8(+) T cells and thus the protective capacity of experimental vaccinations; however, it is currently unknown how the frequency and phenotype of primary (1 degrees ) memory CD8(+) T cells impact the quantity and phenotype of secondary (2 degrees ) memory CD8(+) T-cell populations. Here, we show that 2 degrees infections of mice that received different 1 degrees infections and/or immunizations generated similar numbers of 2 degrees effector and memory CD8(+) T cells. Remarkably, this result was independent of the numbers and phenotype of 1 degrees memory CD8(+) T cells present at the time of rechallenge. However, after adoptive transfer of low numbers of 1 degrees memory CD8(+) T cells, a linear correlation between 1 degrees memory CD8(+) T-cell input and 2 degrees memory CD8(+) T-cell numbers was observed. These data suggest that, above a very low threshold, boosting of 1 degrees memory CD8(+) T-cell populations elicits 2 degrees immune responses of similar magnitude. Therefore, our study has important implications for the design of prime-boost regimens that aim to generate protective CD8(+) T-cell-mediated immunity.
