Word for word copying

Hello everyone, I was adding a citation for one of the sentences where a citation was needed, and I noticed that the second clause of the sentence was copied from the source I found word-for-word. I’m referring to the phrase that reads “with an annual turnover of over $200 million and a selling price of roughly $5000–6000 per kilo as of July 2012” And the 16th reference which goes along with it. Might I suggest the clause be rewritten, or is this alright? I’d make this change myself but I’m new here and I’m not sure if it’s necessary or not. Thanks !

Thanks for pointing out the issue. I made this change in the Introduction with a 2024 source referring to the 2019 market size according to Grand View Research data. I checked some 50 other sources, but they were all commercial research services, which do not make good WP:RS sources for the encyclopedia. Zefr (talk) 04:11, 14 April 2024 (UTC)[reply]

Sources for supposed effects from supplement or topical use

This revert is justified for several reasons:

1. this source is a MDPI publication suspected of predatory publishing; numerous limitations presented in the Discussion give little confidence about the quality of the underlying studies, including weak designs from only a few trials, leading to the conclusion, "the findings in this review should only be considered as preliminary" - which is too uncertain to justify use as a source for health effects on skin during aging. Some 6 other limitations presented by the authors disqualify this publication as a WP:MEDRS source.

2. this review on inflammatory and antioxidant biomarkers concluded that the trials included were poorly designed with low statistical power, and included subjects with different health status, causing high heterogeneity. This is not a WP:MEDRS source.

3. a third source on exercise reports numerous limitations indicating the weak studies analyzed, including small sample sizes, bias, different measures included, inconsistencies in study design, and different amounts of astaxanthin supplementation. This is not a WP:MEDRS source.

Overall, the edit and sources are based on poor-quality studies, and the reviews included do not meet the standards of WP:MEDASSESS, justifying removal of the edit. Zefr (talk) 16:22, 25 September 2024 (UTC)[reply]
