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
Aims and objectives Myocardial infarction (MI) remains a leading cause of mortality and morbidity globally. Timely recognition of symptoms, and understanding of associated risk factors, are critical for early intervention and improved outcomes. However, awareness levels - particularly among the elderly in rural regions - remain poorly studied. This study aimed to assess the awareness of heart attack symptoms and risk factors among the elderly population in rural Chennai. Methodology A cross-sectional study was conducted among 384 individuals, aged 60 years and above, in the rural field practice area of Medavakkam, under Madras Medical College, Chennai, India. An interviewer-administered questionnaire assessed knowledge of 9 symptoms and 11 risk factors associated with MI. Awareness scores were calculated based on participants' spontaneous and prompted responses. Results The mean age of participants was 65 years. Chest pain (248, or 64.58%) and breathlessness (176, or 45.83%) were the most recognized symptoms, while neck pain (12, or 3.12%) was the least known. Among risk factors, hypertension (182, or 47.4%) and stress (178, or 46.35%) were most identified, whereas high salt intake (22, or 5.73%) and obesity (26, or 6.77%) were least known. The average awareness score for symptoms was 5.56, for risk factors, 7.61, and the total knowledge score was 13.18 out of 20. Conclusion The study reveals significant gaps in awareness of heart attack symptoms and risk factors among the rural elderly. These findings underscore the urgent need for community-based health education and preventive strategies, tailored to this vulnerable demographic, to enhance early recognition and reduce MI-related morbidity and mortality.
