Specific and nonspecific diagnoses of dizziness and vertigo in primary care: A descriptive study.
Article in Atencion primaria, 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
objectiveTo study the prevalence and incidence of specific and nonspecific diagnoses of "dizziness" and "vertigo", and their relationships with the characteristics of the population.
designDescriptive cross-sectional study.
settingTwenty primary care teams in Cataluña.
participantsPatients aged 15 years or older. MAIN OUTCOMES: All diagnostic records related to vertigo, classified as nonspecific diagnoses or specific diagnoses and sociodemographic data of the study population during 2019.
resultsAmong 545,938 patients, there were fewer specific diagnoses (1533/10.47%) than non-specific diagnoses (13,111/89.53%), with a higher mean age in diagnosed patients (specific 57.87±16.50; non-specific 57.53±18.74; undiagnosed 50.85±17.75) and a higher proportion of women (66.8% specific; 66.3% non-specific; 50.9% undiagnosed). The most prevalent specific diagnosis was Meniere's syndrome (0.16%), followed by benign paroxysmal positional vertigo (BPPV) (0.11%), but the cumulative annual incidence of BPPV was much higher (0.26% vs. 0.02%). A higher percentage of women than men had specific diagnoses: BPPV (prevalence 0.15% vs. 0.07%/cumulative incidence 0.34% vs. 0.18%), Meniere's syndrome (0.19% vs. 0.13%/0.02% vs. 0.01%) and non-specific diagnoses (2.43% vs. 1.28%/3.18% vs. 1.67%). The ratio of non-specific to specific diagnoses was approximately 9 in both sexes. The characteristics that modified this ratio were deprivation index, age and nationality.
conclusionsThere is a predominance of non-specific vertigo diagnoses, associated with sociodemographic factors. These findings highlight the need to improve the training and awareness of healthcare professionals.
