Dissatisfaction with SUS pharmaceutical services and nonadherence to medication use.
Article in Revista de saude publica, 2025. 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 analyze the association between user dissatisfaction with the pharmaceutical services provided by the Brazilian Unified Health System (SUS) and nonadherence to medication use by patients with chronic non-communicable diseases.
methodsA cross-sectional study with data from the service evaluation component of the Pesquisa Nacional sobre Acesso, Utilização e Promoção do Uso Racional de Medicamentos in Brazil, conducted from July to December 2014. In-person interviews were analyzed with SUS users aged 18 or over who had used medications for hypertension, diabetes, and dyslipidemia and had visited SUS pharmacies in the three months prior to the survey. The dependent variable was medication nonadherence, assessed through three measures: nonadherence due to lack of medication, nonadherence in the past seven days and declared nonadherence. The independent variable was dissatisfaction with the dimensions of pharmaceutical services (timeliness, availability, and accommodation), measured using item response theory. Logistic regression was performed to calculate crude and adjusted odds ratios (OR).
resultsA total of 2,448 users were evaluated. Nonadherence due to lack of medication was 31.6%; in the past seven days was 11.5%; and declared nonadherence 13.0%. Lack of access and forgetfulness were the main reasons for nonadherence in the past seven days. In the adjusted analysis, dissatisfaction with the "timeliness" dimension was associated with nonadherence in the past seven days (OR = 1.489; 95%CI: 1.023-2.168) and the "accommodation" dimension was associated with declared nonadherence (OR = 3.132; 95%CI: 2.266-4.329).
conclusionDissatisfied users were more likely to be nonadherent to medication use across all service dimensions, and dissatisfaction with the availability and accommodation of pharmaceutical services was associated with nonadherence.
