Impact of COVID-19 pandemic on the surgical treatment of gastric cancer.
Article in Clinics (Sao Paulo, Brazil), 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 papers.
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.
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
objectiveThe Coronavirus Disease 2019 (COVID-19) pandemic has been recognized as one of the most serious public health crises. This study aimed to evaluate the short-term impact of the pandemic on the surgical treatment of patients with gastric cancer (GC) in addition to their clinicopathological characteristics. We also verified adherence to the COVID-19 screening protocol adopted in the institution.
methodsAll patients with GC who underwent surgical treatment between 2015 and 2021 were retrospectively evaluated and divided into two groups according to the time period: control group (2015-2019) and COVID group (2020-2021). The institutional protocol recommends that patients referred for surgery undergo RT-PCR for severe acute respiratory syndrome coronavirus 2 infection.
resultsA total of 83 patients were classified into the COVID group and 535 into the control group. The number of surgical procedures performed in the control group was 107 (SD±23.8) per year. Diagnostic procedures (p=0.005), preoperative chemotherapy (p<0.001), and adenocarcinomas without Lauren's subtype (p=0.009) were more frequent in the COVID group than in the control group. No significant difference was observed in the pathological characteristics and surgical outcomes of curative GC between the two groups. Evaluation of protocol compliance showed that of 83 patients with GC in the COVID group, 19 (22.9%) were not tested for COVID-19 before surgery. Two patients tested positive for COVID-19 (one preoperative and one postoperative).
conclusionA decrease in the average number of surgeries and a higher frequency of diagnostic procedures occurred during the pandemic than in the previous time period. Tumor/node/metastasis classification, morbidity rates, and mortality rates in patients with GC during the pandemic did not differ from those in the previous time period. Accordingly, GC surgical treatment with acceptable screening protocol compliance could be safely performed during the COVID-19 pandemic.
