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

purposeBariatric/metabolic surgery has been reported to reduce the incidence of severe coronavirus disease 2019 (COVID-19); however, its ability to reduce risk is controversial. Therefore, this study aimed to elucidate the incidence and severity of COVID-19 in bariatric patients in Japan.

methodsThe first survey of patients infected with COVID-19 after bariatric/metabolic surgery until June 30, 2022, was sent to 83 Japanese institutions. A second survey was conducted in institutions that reported on COVID-19 patients. The severity of COVID-19 was compared between the general population and bariatric patients, and risk factors correlated with severity were also evaluated.

resultsTwenty-six institutions (31.3%) reported 119 patients with COVID-19 after laparoscopic bariatric/metabolic surgery. There were no severe cases or deaths; however, moderate COVID-19 (pneumonia) was significantly more common in bariatric patients than in the general population (11.4% vs. 1.3%). The risk factors for moderate COVID-19 in bariatric patients included incurable dyslipidemia and infection before the 6th wave of the pandemic.

conclusionIn Japan, the number of moderate COVID-19 cases may be higher in bariatric patients than in the general population. This study did not show that bariatric/metabolic surgery reduces the risk of COVID-19 complications.
