[Prevalence of microbiologically-confirmed influenza in patients with influenza-like illness in primary care and clinical and epidemiological characteristics].

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
objectiveWe evaluated the prevalence of microbiologically-confirmed influenza infection among patients with influenza-like symptoms and compared the clinical and epidemiological characteristics of patients with and without influenza infection.
methodsRetrospective study of a cohort of patients with influenza-like symptoms from 2016 to 2018 who participated in a clinical trial in thirteen urban primary centres in Catalonia. Different epidemiological data were collected. Patients rated the different symptoms and signs on a Likert scale (absent, little problem, moderate problem and severe problem) and self-reported the measure of health status with the EuroQol visual analogue scale. A nasopharyngeal swab was taken for microbiological isolation of influenza and other microorganisms.
resultsA total of 427 patients were included. Microbiologically confirmed influenza was found in 240 patients (56.2%). The percentage of patients with moderate-to-severe cough, muscle aches, tiredness and dizziness was greater among patients with microbiologically confirmed influenza. The self-reported health status was significantly lower among patients with true flu infection (mean of 36.3 ± 18.2 vs 41.7 ± 17.8 in patients without influenza; p<0.001).
conclusionsClinical findings are not particularly useful for confirming or excluding the diagnosis of influenza when intensity is not considered. However, the presence of moderate-to-severe cough, myalgias, tiredness and dizziness along with a poor health status is more common in patients with confirmed flu infection.
