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

backgroundBariatric surgery (including gastric bypass) is associated with long-term deficiencies in vitamins and minerals, which may have deleterious effects on physiology. The American Association of Clinical Endocrinologists' (AACE) guidelines regarding post-operative vitamin supplementation have recently been endorsed by the International Federation for the Surgery of Obesity and Metabolic Disorders (IFSO). Supplements have cost implications. Non-branded multivitamins may have similar compositions to branded multivitamins, but at a lower cost. This study assesses multivitamin supplementation following bariatric gastric bypass in England against AACE guidelines. It also examines the composition and cost of branded and non-branded multivitamins.

methodsMicronutrient amounts in common multivitamin preparations were obtained from product literature. Costs were collected from a standard retailer. To determine vitamin prescribing patterns, the 37 NHS hospitals performing bariatric gastric bypasses in England were contacted. Practice was assessed against AACE guidelines.

resultsAll non-branded multivitamins met AACE guidelines for composition. Most had similar compositions to branded multivitamins, and all were cheaper. There was no standard practice regarding post-operative supplementation among the 35 responding hospitals. Only 7/35 (20%) hospitals followed the guidance for two-tablet doses of multivitamins. Immediately post-operatively, 25/35 (71%) hospitals administered calcium carbonate and vitamin D (none recommended calcium citrate, as recommended by AACE to improve absorption), and only 9/35 (26%) hospitals recommended iron to all patients.

conclusionMost non-branded multivitamins are lower cost alternatives to branded multivitamins, with similar compositions. The AACE recommendation for two-tablet doses of multivitamins is not being met by most English centres. Calcium and iron supplementation is also inadequate.
