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

As the field of gene therapy advances and as the importance of sex as a biological variable in shaping viral immune responses is recognized, the impact of sex on adeno-associated virus (AAV) vectors mediated gene therapies remain largely unexplored. Here we review current understanding of the immune response against AAV gene therapy as well as the knowledge of sex differences observed in viral responses. We discuss sex differences in innate immune mechanisms such as Toll-like receptor recognition and complement activation, as well as the functional responses of key immune cells such as dendritic cells, macrophages, and T/B cells that are involved in AAV immunogenicity. Variations in pre-existing immunity, including differences in antibody levels and neutralizing activity among sexes, are also described. Additionally, we investigate evidence in the literature of sex differences in AAV transduction in animal and suggest a potential link between the immune responses and higher transductions in males.
