1 · What the graph read from it

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.

2 · The registry

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

introductionChagas disease (CD) is caused by the protozoan parasite

methodsIn this cohort study from 2006 to 2022, the authors identified patients with CD by screening the electronic medical record for International Classification of Diseases, 9th Revision and 10th Revision codes. The authors obtained demographic, medical history, electrocardiographic, echocardiographic, and pharmacy data. Adverse outcomes, including all-cause mortality, heart failure hospitalization, and heart transplantation, were identified by database programming and confirmed by manual chart review.

resultsThere were 53 cases of CD in total, and 75% of patients self-identified as Hispanic. The mean age was 49 years old, and 45% were female. Dyslipidemia (45%) and hypertension (32%) were common comorbidities. A total of 7 patients (13%) had a left ventricular ejection fraction < 45%. During the follow-up period, adverse outcomes included 4 cardiovascular deaths, 5 heart failure hospitalizations, and 4 heart transplantations. The prevalence of diagnosed CD in the Kaiser Permanente Northern California population has risen from 0.22 per 100,000 persons from 2006 to 2010 to 0.70 per 100,000 persons from 2018 to 2022. DISCUSSION: The prevalence of diagnosed CD in Kaiser Permanente Northern California increased during the study period, and patients with CD frequently had poor cardiovascular outcomes, likely due to the patients presenting with advanced disease.

conclusionSystematic screening and awareness are likely to facilitate early diagnosis and improve treatment to avoid chronic complications of CD.
