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

backgroundBiologically based complementary and alternative medicine (BBCAM) includes special diets, dietary supplement and herbal remedies, not prescribed by a doctor or dietitian. The use of BBCAM is common among cancer survivors. BBCAM can interact with conventional treatments and unregulated products may cause harm. This study aimed to determine the prevalence, types, and motivations for BBCAM use among cancer survivors.

methodsA survey assessed clinical characteristics and BBCAM use in participants >18 yrs who had received cancer treatment in Ireland from 2018 to 2022.

resultsAmongst 295 respondents (77% female, mean age 53 yrs), BBCAM use increased from 28% pre-diagnosis to 34% post-diagnosis (p < 0.001). For BBCAM users (n = 97, 33%), "daily-use" increased from 38% to 72% (p < 0.001) post-diagnosis. Common types included: mineral/vitamin supplements (84%), dietary supplements (e.g. turmeric, coenzyme-Q10) (78%), herbal remedies/botanicals (e.g. mistletoe, St. John's Wort, echinacea, ginseng) (50%), cannabis (21%), and other natural products (laetrile, shark cartilage, apricot kernels) (19%). Biological medicines (GcMAF, immuno-augmentative therapy) were used by 12% of BBCAM users. Special diets including dairy free (32%), gluten-free (19%), intermittent fasting (17%), ketogenic diet (15%), juicing/detox (10%) were also common. Perceived benefits included: improved well-being (63%) and reduced psychological stress (59%).

conclusionBBCAM use increases after a cancer diagnosis. Patient perceived benefits highlight potential gaps in the current healthcare model, indicating a need for greater emphasis on safe survivorship care.
