Prevalence and determinants of silent myocardial ischemia in patients with type 2 diabetes in Cameroon: a cross-sectional study.
Article in The Pan African medical journal, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
Introduction: diabetes mellitus is a major health problem worldwide. It is associated with high cardiovascular morbi-mortality especially coronary artery disease. Myocardial ischemia is often asymptomatic (silent myocardial ischemia) in people with type 2 diabetes mellitus thus making early diagnosis difficult. Silent myocardial ischemia is defined as the objective evidence of myocardial ischemia in the absence of chest discomfort or other angina equivalents. This study aimed to determine the prevalence and determinants of silent myocardial ischemia in a population of people with type 2 diabetes using exercise stress electrocardiography. Methods: we carried out a cross-sectional study between January and April 2019 at the National Obesity Centre of the Yaounde Central Hospital. Patients with type 2 diabetes underwent a complete clinical evaluation, blood test, resting electrocardiogram (ECG), and exercise stress ECG according to the Bruce protocol. A positive stress test was defined as horizontal or down-sloping ST depression ≥ 1mm or upsloping ST depression of 2 mm or more 0.06 to 0.08 seconds after the J point. Results: a total of 112 patients with diabetes (63 males and 49 females) were screened. The median age was 58 (IQR: 51 - 64) years. The median time from diabetes diagnosis was 8 (IQR: 5 - 12) years. Fifty-seven (50.4%) had hypertension, 78 (69.0%) had dyslipidemia, 66 (58.4%) were obese, 70 (61.9%) had poor glycemic control, and 23 (20.2%) were smokers. Sixty-five (58%) patients had a positive exercise stress ECG test. Factors independently associated with a positive stress test were abdominal obesity (aOR: 4.2, [95% CI: 1.4 - 12.8]) and Female sex (aOR: 2.5, [95% CI: 1.1 - 5.7]). Conclusion: the prevalence of silent myocardial ischemia was high in a population of asymptomatic patients. This was independently associated with abdominal obesity and female sex.
