1 · What the graph read from it

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.

2 · The registry

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

backgroundNutritional supplements, such as Seatone, which contain freeze-dried tissue from the New Zealand green-lipped mussel Perna canaliculus, are sold in many countries to relieve arthritic symptoms and to aid in the regeneration of arthritic and injured joints.

methodsSearches for all published controlled trials on the clinical effectiveness of green-lipped mussel, as a nutritional supplement with potential health benefits for arthritis, were carried out from four independent databases. No language restrictions were imposed, and the review was undertaken from extracted data and was assessed critically according to predefined criteria by the authors.

resultsReports of clinical studies, using freeze-dried mussel powder, show mixed outcome measures and are not conclusive, with only two of five randomized controlled trials attesting benefits for rheumatoid and osteoarthritis patients. Similarly, animal studies have likewise yielded mixed findings. In both these cases possibly due to the lack of stabilization of the omega-3 polyunsaturated fatty acids, now known to be the basis of anti-inflammatory activity.

conclusionThere is little consistent and compelling evidence, to date, in the therapeutic use of freeze-dried green-lipped mussel powder products for rheumatoid or osteoarthritis treatment, particularly in comparison to other cheaper alternative nutriceutical supplements of proven efficacy. However, further investigations are necessary to determine whether green-lipped mussel supplements, such as Seatone, are therapeutic options in the management of arthritis.
