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

aimCancer surgery in the COVID-19 pandemic presents many new challenges. For each patient, the risk of contracting COVID-19 during the perioperative period, with the potential for life-threatening sequelae (1), has to be weighed against the risk of delaying treatment. We assessed the response and short-term outcomes from elective colorectal cancer surgery during the pandemic at our institution.

methodWe report a prospective cohort study of all elective colorectal surgery cases performed at our Trust during the 11 weeks following the national UK lockdown on 23rd March 2020, compared with the same time period in 2019.

resultsEighty-five colorectal operations were performed during the 2020 (COVID) time period, and 179 performed in the 2019 (non-COVID) time period. A significantly higher proportion of cases during the COVID period were cancer-related (66% vs 26%, p < 0.00001). There was no difference in length of hospital stay, complications or readmissions. There were no mortalities in either cohort. Among the cancer patients, there were no differences in TMN staging, R1 resection rate or lymph node yields. No elective patient tested positive for COVID-19 during the perioperative period.

conclusionAt the height of the COVID pandemic, we maintained delivery the of high-quality elective colorectal cancer surgery, with no worsening of short-term outcomes and no compromise in the quality of cancer resections. Ongoing monitoring of this cohort is essential. The risks associated with COVID-19 will continue for some time, necessitating adaptive responses to maintain high-quality cancer services.
