Epidemiological patterns of acute respiratory illnesses in a tertiary center in Riyadh, Saudi Arabia.
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 1 paper.
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
backgroundAcute respiratory illnesses (ARIs) are a major public health concern and are ranked by the World Health Organization among the leading causes of death worldwide.
objectivesTo determine the positivity proportion, clinical presentation, and risk factors associated with major respiratory viruses, including Influenza A, Influenza B, respiratory syncytial virus
designRetrospective study conducted between October 2022 and March 2023. SETTINGS: Single center tertiary hospital in Riyadh, Saudi Arabia. PATIENTS AND
methodsNasopharyngeal swabs (NPS) were collected from patients with ARI and tested for Influenza A
main outcome measuresEpidemiological and clinical characteristics of patients with positive PCR results. SAMPLE SIZE: 4526 patients with ARI underwent NPS for viral PCR screening.
resultsAmong study population, 537 (11.9%) patients tested positive for at least one of the targeted respiratory viruses. RSV was the predominant pathogen among pediatric patients (n=195, 62.2%), particularly in infants younger than six months. In adults, SARS-CoV-2 was most common (n=98, 44.1%), followed by Influenza A and B. RSV infection was significantly associated with lower respiratory tract involvement (
conclusionRSV, Influenza, and SARS-CoV-2 remain significant causes of ARIs in Riyadh, Saudi Arabia, showing distinct age and seasonal patterns. The results underscore the importance of targeted vaccination and strengthened surveillance to protect high-risk groups. LIMITATIONS: The study was limited by its single-center design and short six-month duration.
