Blood Pressure Treatment Adherence and Control after Participation in the ReHOT.
Trial report in Arquivos brasileiros de cardiologia, 2016. 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
background: Lack of adherence to pharmacological treatment is one of the main causes of low control rates in hypertension.
objective: To verify treatment adherence and associated factors, as well as blood pressure (BP) control in participants of the Resistant Hypertension Optimal Treatment (ReHOT) clinical trial.
method: Cross-sectional study including all 109 patients who had completed the ReHOT for at least 6 months. We excluded those participants who failed to respond to the new recruitment after three phone contact attempts. We evaluated the BP control by ambulatory BP monitoring (ABPM; controlled levels: 24-hour systolic and diastolic BP < 130 x 80 mmHg) and analyzed the patients' treatment adherence using the Morisky Medication Adherence Scale (MMAS) questionnaire validated by Bloch, Melo, and Nogueira (2008). The statistical analysis was performed with the software IBM SPSS statistics 21.0. We tested the normality of the data distribution with kurtosis and skewness. The variables tested in the study are presented with descriptive statistics. Comparisons between treatment adherence and other variables were performed with Student's t test for independent variables and Pearson's chi-square or Fisher's exact test. To conduct analyses among patients considering adherence to treatment and BP control, we created four groups: G0, G1, G2, and G3. We considered a 5% significance level in all tests.
results: During the ReHOT, 80% of the patients had good BP control and treatment adherence. Of 96 patients reevaluated in the present study, only 52.1% had controlled hypertension when assessed by ABPM, while 31.3% were considered adherent by the MMAS. Regarding other ABPM measures, we observed an absence of a nocturnal dip in 64.6% of the patients and a white-coat effect and false BP control in 23% and 12.5%, respectively. Patients' education level showed a trend towards being a determinant factor associated with lack of adherence (p = 0.05). Resistant hypertension and number of medications were significantly associated with BP control assessed by ABPM (p = 0.009 and p = 0.001, respectively). Resistant hypertension was also significantly associated with group G0 (patients with no control or adherence, p = 0.012).
conclusion: There was a decrease in BP control and adherence measured by the MMAS after participation of at least 6 months in the ReHOT clinical trial. FUNDAMENTO:: A falta de adesão ao tratamento medicamentoso da hipertensão arterial sistêmica (HAS) é uma das principais causas das baixas taxas de controle da doença. OBJETIVO:: Verificar a adesão e fatores relacionados a ela, além do controle pressórico de pacientes que participaram do ensaio clínico Resistant Hypertension Optimal Treatment (ReHOT). MÉTODO:: Estudo transversal que incluiu todos os 109 pacientes que concluíram o ReHOT há pelo menos 6 meses. Foram excluídos aqueles que não responderam ao novo recrutamento após três tentativas de contato telefônico. Foi realizada avaliação do controle pressórico através de monitorização ambulatorial da pressão arterial (MAPA; PA controlada: pressão arterial [PA] sistólica e diastólica de 24 horas < 130 x 80 mmHg) e avaliação da adesão através de respostas ao questionário Morisky Medication Adherence Scale (MMAS) validado por Bloch, Melo e Nogueira (2008). A análise estatística foi realizada com o programa IBM SPSS statistics 21.0. Para verificar a normalidade da distribuição dos dados, utilizamos testes de curtose e assimetria. As variáveis relacionadas ao objeto de estudo são apresentadas por meio de estatística descritiva. Comparações entre a adesão ao tratamento e demais variáveis foi realizada com o teste t de Student para variáveis independentes e teste do qui-quadrado de Pearson ou exato de Fisher. Para a análise entre pacientes considerando a adesão ao tratamento e controle da PA, foram criados quatro grupos: G0, G1, G2 e G3. Em todos os testes estatísticos consideramos um nível de significância de 5%. RESULTADOS:: Durante o ReHOT, 80% dos pacientes apresentaram controle pressórico e adesão ao tratamento. Do total de 96 pacientes reavaliados, apenas 52,1% foram identificados como tendo HAS controlada através da avaliação da MAPA e 31,3% apresentaram adesão pelo MMAS. Quando consideradas outras medidas da MAPA, verificou-se que 64,6% dos pacientes não apresentavam descenso noturno e 23% e 12,5% apresentavam efeito do avental branco e falso controle da PA, respectivamente. A escolaridade apresentou tendência a ser um fator determinante de falta de adesão (p = 0,05). O número de medicamentos e a HAS resistente (HAR) tiveram uma relação significativa com o controle da PA medida por MAPA (p = 0,009 e p = 0,001, respectivamente). A HAR teve relação significativa com o grupo G0 (sem controle e sem adesão, p = 0,012). CONCLUSÃO:: Houve redução do controle da PA e da adesão pelo MMAS após pelo menos 6 meses de participação no ensaio clínico ReHOT.
