Impact of the COVID-19 Pandemic on Cancer Care: A Global Collaborative Study.
Article in JCO global oncology, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT04712292 (Effects of the COVID-19 Pandemic on the Diagnosis, Treatment and Outcomes of Patients Affected by Colorectal Cancer Requiring Surgery), which is not on this map. Cited by 182 papers, 7 of them syntheses 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.

Abstract
purposeThe COVID-19 pandemic affected health care systems globally and resulted in the interruption of usual care in many health care facilities, exposing vulnerable patients with cancer to significant risks. Our study aimed to evaluate the impact of this pandemic on cancer care worldwide.
methodsWe conducted a cross-sectional study using a validated web-based questionnaire of 51 items. The questionnaire obtained information on the capacity and services offered at these centers, magnitude of disruption of care, reasons for disruption, challenges faced, interventions implemented, and the estimation of patient harm during the pandemic.
resultsA total of 356 centers from 54 countries across six continents participated between April 21 and May 8, 2020. These centers serve 716,979 new patients with cancer a year. Most of them (88.2%) reported facing challenges in delivering care during the pandemic. Although 55.34% reduced services as part of a preemptive strategy, other common reasons included an overwhelmed system (19.94%), lack of personal protective equipment (19.10%), staff shortage (17.98%), and restricted access to medications (9.83%). Missing at least one cycle of therapy by > 10% of patients was reported in 46.31% of the centers. Participants reported patient exposure to harm from interruption of cancer-specific care (36.52%) and noncancer-related care (39.04%), with some centers estimating that up to 80% of their patients were exposed to harm.
conclusionThe detrimental impact of the COVID-19 pandemic on cancer care is widespread, with varying magnitude among centers worldwide. Additional research to assess this impact at the patient level is required.
