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
backgroundCardiac arrest remains a leading cause of mortality worldwide. Advanced Cardiovascular Life Support (ACLS) training is designed to equip postgraduate (PG) residents with the competencies required for effective resuscitation. However, gaps in skill retention, electrocardiogram (ECG) interpretation, and utilization of physiological monitoring tools such as end-tidal carbon dioxide (EtCO₂) monitoring and real-time cardiopulmonary resuscitation (CPR) feedback devices continue to impede resuscitation quality in clinical practice.
aimThe aim of the study is to assess post-training confidence, perceived clinical competence, and guideline adherence among PG residents and to identify challenges encountered during live in-hospital cardiac arrest resuscitations.
methodsA cross-sectional, feedback-based study was conducted at a tertiary care, American Heart Association (AHA)-accredited teaching hospital in South India over six months. A total of 187 PG residents from 32 departments who had completed ACLS training and participated in at least one in-hospital cardiac arrest resuscitation were enrolled. A validated, structured 24-item questionnaire (Cronbach's α = 0.814) was administered electronically. This study was reported in accordance with the STROBE (Strengthening the Reporting of Observational Studies in Epidemiology) checklist for cross-sectional studies. Statistical analysis included descriptive statistics, Mann-Whitney U test, Spearman correlation, and multiple linear regression.
resultsMean confidence and perceived competence scores were 9.75 ± 1.33 (95% confidence interval (CI): 9.55-9.94) and 22.83 ± 3.29 (95% CI: 22.35-23.31), respectively (all values self-reported). Significant gaps in monitoring tool utilization were identified, including non-use of real-time CPR feedback devices, absence of EtCO₂ monitoring, and difficulties with ECG rhythm interpretation during live resuscitations. Specifically, 43.5% (n = 80) of participants did not use real-time CPR feedback devices, and 48.9% (n = 89) did not utilize EtCO₂ monitoring during resuscitation. The most prevalent resuscitation challenge was ECG rhythm interpretation, reported by 34.2% (n = 64; 95% CI: 27.3%-41.9%) of participants. ACLS training quality was rated as excellent by 73% (n = 137; 95% CI: 65.8%-79.3%) of participants. No significant intergroup differences were found between clinicians and non-clinicians (p > 0.05). Confidence was the only significant predictor of perceived clinical competence (β = 0.724, p < 0.001; R² = 0.527).
conclusionParticipants reported high levels of confidence and perceived clinical competence following ACLS training, suggesting the program provides a solid foundation for emergency cardiovascular care. Nonetheless, persistent deficiencies in ECG interpretation, feedback device utilization, and EtCO₂ monitoring adherence warrant targeted curricular interventions, including structured ECG modules, biannual simulation-based refresher training, and mandatory integration of physiological monitoring tools. Future multicenter studies with objective performance metrics are recommended.
