PMID 33084780WHAT IT FOUND
17 experts and 12 patients rated a breast radiotherapy manual mostly acceptable, but items E and G did not reach the 80% minimum and were revised.
Key findings
0117 experts rated the manual in three blocks, with averages of 89.07%, 92.94% and 93.13% agreement, above the 80% minimum.
02Items E and G reached 70.58% agreement, below the 80% minimum.

What it does not show
The study did not test patient outcomes. Items E and G reached 70.58% agreement, below the 80% minimum, and the paper reports revision but no revalidation. The appearance validation used 12 women, which the authors call a small number. Participants were selected intentionally, not randomly, and experts were chosen from the research group's contacts. The deodorant avoidance advice is included in the manual, but the paper says there is no consensus and further studies are needed.
The easy way to misread this
Do not read this as evidence that the manual improves patient self-care, anxiety, or radiotherapy side effects. The study only asked 17 experts and 12 patients to rate the manual's content and appearance, and it did not test patient outcomes.
