Prevalence of long covid symptoms in Tuscany, Italy: a population-representative cross-sectional telephone survey.
Article in BMJ open, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
objectivesLong covid affects over 36 million individuals in the European region, but its clinical profile is still poorly defined, particularly in the general population with less severe acute disease. This study aimed to assess the prevalence of a broad spectrum of symptoms potentially linked to long covid in the general population of Tuscany, Italy.
methodsA cross-sectional study was conducted in January-February 2024 using Computer-Assisted Telephone Interviews in a representative population sample of Tuscany. Based on the WHO questionnaire long covid symptom list, data on 33 symptoms experienced in the past 6 months were collected, along with demographic and clinical characteristics. After excluding patients with COVID-19 within the past 6 months and those failing a screening cognitive test, symptom prevalence and ORs adjusted for sex, time since infection, smoking and concurrent diseases (aOR) were calculated according to COVID-19 history.
resultsAfter excluding 129 failing the cognitive test (6.4%) and 123 recent COVID cases (6.1%), among 1753 participants interviewed, 1013 (57.8%) had a history of COVID-19. The symptoms significantly more prevalent in individuals with previous COVID-19 were fatigue (12.8% vs 8.9%, aOR 1.6 (95% CI 1.2 to 2.2)), concentration impairment (5.5% vs 2.4%, aOR 2.2 (95% CI 1.3 to 3.8)) and skin rashes (4.5% vs 2.4%, aOR 1.9 (95% CI 1.1 to 3.3)). Prevalences and ORs were higher in more recent COVID-19 cases, particularly females and individuals with concurrent diseases.
conclusionsWe identified in a population-based study some symptoms significantly more common in individuals with previous COVID-19. This approach complements data collected in clinical settings and in patients selected by greater disease severity. The findings may help future surveillance efforts and targeted public health interventions directed at optimising care pathways and mitigating long-term consequences.
