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

backgroundWhile extensive data are available on the postponement of elective surgical procedures due to the COVID-19 pandemic for Germany, data on the impact on emergency procedures is limited.

methodsIn this retrospective case-control study, anonymized case-related routine data of a Germany-wide voluntary hospital association (CLINOTEL association) of 66 hospitals was analyzed. Operation volumes, in-hospital mortality, and COVID-19 prevalence rates in digestive surgery procedure groups and selected single surgical procedures in the one-year periods before and after the outbreak of the COVID-19 pandemic were analyzed. The analysis was stratified by admitting department (direct admission or transfer to the general surgical department, i.e., primary or secondary surgical patients) and type of admission (elective/emergent).

resultsThe total number of primary and secondary surgical patients decreased by 22.7% and 11.7%, respectively. Among primary surgical patients more pronounced reductions were observed in elective (-25.6%) than emergency cases (-18.8%). Most affected procedures were thyroidectomies (-30.2%), operations on the anus (-24.2%), and closure of abdominal hernias (-23.9%; all P's < 0.001). Declines were also observed in colorectal (-9.0%, P = 0.002), but not in rectal cancer surgery (-3.9%, n.s.). Mortality was slightly increased in primary (1.3 vs. 1.5%, P < 0.001), but not in secondary surgical cases. The one-year prevalence of COVID-19 in general surgical patients was low (0.6%), but a significant driver of mortality (OR = 9.63, P < 0.001).

conclusionsCompared to the previous year period, the number of patients in general and visceral surgery decreased by 22.7% in the first pandemic year. At the procedure level, a decrease of 14.8% was observed for elective procedures and 6.0% for emergency procedures. COVID-19 infections in general surgical patients are rare (0.6% prevalence), but associated with high mortality (21.8%).

trial registrationThe present study does not meet the ICMJE definition of a clinical trial and was therefore not registered.
