It is odd that the abstract does not discuss the effect of this intervention on blood pressure readings. When digging down to the results table, it is apparent that actual systolic and diastolic readings showed no effect; if this is why they didn't mention it in the abstract, that is not a best practice of ethical reporting.
Nicely done study by Italian researchers, and encouraging to see a no-cost, non-pharmaceutical intervention with some effect. The abstract could have been improved by mentioning how many studies resulted from the original search, and whether they followed PRISMA guidelines.
Radiation centers typically only recommend a low fiber diet to treat radiation-induced diarrhea, so it is good to see apparently high-quality studies addressing nutritional supplements for this problem.
This is a nicely designed and written study, freely available online, but I am puzzled as to how the Na/K ratio was calculated, as their sample had ratios around 4-6, whereas most ratios you see in other studies are about 20-30. They do not explain this step in the otherwise well-described methods.
This journal helpfully provides hyperlinks for various terms used in the abstracts, plus includes "Section snippets" that function as an expanded abstract. Very nice.
