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

This study reviews the prevalence of copper (Cu) deficiency in patients for metabolic and bariatric surgery (MBS), as well as the long-term outcomes related to the prevalence of Cu deficiency after undergoing MBS. A systematic literature search and meta-analysis were conducted in PubMed, Web of Science, and Scopus for articles published by August 31, 2024. The search terms included metabolic and bariatric surgery, weight loss surgery, metabolic surgery, obesity surgery, sleeve gastrectomy, gastric banding, gastric bypass, duodenal switch, duodenojejunal bypass, copper, copper deficiency, and hypocuposemia. After PRISMA screening, 43 studies with a total of 49 patients with obesity were included in this meta-analysis. The results demonstrated that the prevalence of Cu deficiency after MBS at 1-, 2-, 3-, and 4-year follow-up was found to be 16%, 28%, 21%, and 16%, respectively. Additionally, hypocuposemia was observed to be more prevalent in patients with BPD compared with other types of surgery. Copper deficiency is frequently observed in patients following MBS, particularly those who have undergone BPD procedures. Therefore, it is imperative for patients to undergo postoperative follow-up and nutritional monitoring, along with targeted interventions.
