Mycobacterium bovis bacille Calmette-Guerin-derived extracellular vesicles as an alternative to live BCG immunotherapy.
Article in Clinical and experimental medicine, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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.
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
For over 40 years, the gold standard treatment for non-muscular invasive bladder cancer (NMIBC) has been repeated administration of Mycobacterium bovis bacille Calmette-Guerin (BCG). Upon administration, BCG initiates a cascade of immunological events that lead to the recruitment of immune cells to the bladder that eliminates NMIBC cells in a multi-mechanistic, yet incompletely defined manner. Despite its effectiveness, live BCG immunotherapy is often impacted by limited supply and availability and can cause rare but serious side effects. Bacterial extracellular vesicles (EV) are nanoparticles secreted by live bacteria. EVs are composed of multiple surface proteins, sugars, and lipid that can elicit cellular responses and host recognition similar to live bacteria. In this study, we sought to evaluate the cellular responses of epithelial bladder cancer cells (BCC) to BCG EVs and live BCG. We compared the effect of each treatment on BCC cytokine production, cellular viability and apoptosis. Our data suggest that BCG EVs are as effective as live BCG in eliciting cytokine responses and halting cancer cell growth by, in part, inducing apoptosis. These results indicate that BCG EVs warrant investigation as an alternative to live BCG for NMIBC immunotherapy.
