Kind: research · Impact: low

## In brief

- A study published in Scientific Reports, hosted on nature.com, reports that hidden baseline heterogeneity can mask treatment effects in randomized xenograft studies.
- The available source is a feed entry with no summary, so methods, sample sizes and results could not be verified.

## Why it matters

If baseline differences between animal tumour groups go unnoticed, real treatment effects can be hidden, which affects how researchers interpret xenograft results.
