Clinical features of Omicron variant infection in 445 patients with coronavirus 19 disease.
Article in Annals of Saudi medicine. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
backgroundSevere acute respiratory syndrome coronavirus-2 (SARS-CoV-2) can mutate frequently and many new strains have emerged thus far. The clinical and epidemiological characteristics differ with each dominant strain.
objectivesObtain an understanding of the clinical characteristics of patients infected with the Omicron variants of the SARS CoV-2.
designRetrospective cohort SETTINGS: Teaching hospital in China. PATIENTS AND
methodsData on sociodemography, signs/symptoms, hospital stay, viral shedding period, comorbidities, treatment options and final outcome were retrieved from hospital electronic medical record. We collected nasopharyngeal samples, laboratory data, and clinical data from patients admitted to the hospital with SARS CoV-2.
main outcome measuresClinical characteristics of the patients infected with Omicron variant of SARS CoV-2. SAMPLE SIZE: 445 patients
resultsThe median age was 43.0 years with a range from 2 to 75 years. Two-thirds of the participants were male and one-third were female. Almost half of the participants (51.9%) had no symptoms, whereas 48.1% had at least one symptom. Of symptomatic patients, 26.7% had mild symptoms and 21.3% had moderate symptoms. No patients were admitted with severe or critical symptoms. All patients discharged from the hospital after complete recovery without any serious complications or death. The most common symptom was cough followed by sore throat and fever. Less common symptoms were having sputum, stuffy nose, and muscle pain. Rare symptoms were weakness, headache, diarrhea, hemoptysis and nausea/vomiting.
conclusionsAll patients had mild to moderate symptoms. Shortness of breath was not a common symptom among the study group. No patients needed invasive oxygen therapy in this cohort. LIMITATIONS: Single center and retrospective design. CONFLICT OF INTEREST: None.
