Did the COVID-19 lockdown result in a delay of colorectal cancer presentation and outcomes? A single centre review.
Article in Langenbeck's archives of surgery, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers, 1 of them a synthesis that pooled 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.
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
purposeThe COVID-19 pandemic and resultant lockdown measures potentially delay management of non-communicable, life-limiting diseases like colorectal cancer (CRC) through avoidance of healthcare facilities by the public and diversion of resources within healthcare systems. This study aims to evaluate the impact of Singapore's "Circuit Breaker (CB)" lockdown measures on CRC disease presentation and short-term surgical outcomes, while comparing Singapore's approach against other countries which employed similar lockdown measures.
methodsPatients whose initial diagnosis of CRC was made within the 6-month pre-CB (6/10/19-6/4/20) ("pre-CB group") and post-CB (7/4/20-7/10/20) ("post-CB group") period were enrolled retrospectively. The groups were compared based on severity of disease on presentation and short-term operative outcomes.
resultsIn total, 105 patients diagnosed with CRC were enrolled in this study. When comparing pre-CB and post-CB groups, there was no significant difference in stage of CRC on presentation (p = 0.850). There was also no increase in need for emergent operations (p = 0.367). For patients who had undergone an operation, postoperative morbidity was not significantly higher in the post-CB group (p = 0.201). Both groups of patients had similar length of stay in the hospital (p = 0.438).
conclusionUnlike similar high-income countries, Singapore did not see later stage disease on presentation and poorer operative outcomes after lockdown measures. Possible reasons include lesser healthcare avoidance behaviours amongst Singaporeans, and adequate preparation of resources and contingency plans formed by hospitals after previous pandemics.
