COVID-19 in a remote First Nations community in British Columbia, Canada: an outbreak report.
Article in CMAJ open. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
backgroundIn April 2020, British Columbia experienced its first outbreak of COVID-19 in a remote First Nations community. The objective of this paper was to describe the outbreak, including epidemiological and laboratory findings, and the public health response.
methodsThis report summarizes an outbreak of COVID-19 on Cormorant Island, British Columbia, in March and April 2020. Confirmed cases underwent investigation and contact tracing. Supports were provided to ensure successful isolation and quarantine for cases and contacts. Messaging to the community was circulated by trusted community members. Descriptive and social network analyses were conducted to describe the outbreak as it evolved. All case specimens underwent whole-genome sequencing.
resultsThirty cases of SARS-CoV-2 infection were identified. Those infected had a median age of 34 years (range 15-77), and the majority identified as female (19, 63%) and as First Nations (27, 90%). The most common symptoms included chills, cough, diarrhea, headache and fever. Five people were hospitalized (17%) and 1 died (3%). Percent positivity in the community was 18%. Transmission occurred primarily during evening social gatherings and within households. Two weeks after control measures were initiated, no further cases were identified. All cases were genetically related by 2 single nucleotide polymorphisms or fewer, and they belonged to the most dominant SARS-CoV-2 lineage present in British Columbia in April 2020.
interpretationA community-led response was essential for the effective containment of this outbreak that included 30 cases, preventing onward transmission of the virus. Lessons learned from the management of this outbreak can inform response to other similar outbreaks in First Nations communities across Canada.
