Many medical postgraduate students exhibit a lack of clarity in their understanding of relevant statistical concepts during the conduct of diagnostic studies. ⋯ By drawing analogies between basic concepts in diagnostic tests and concepts in statistics, this article helps to enhance researchers' abilities in designing and interpreting clinical diagnostic studies, thereby improving the quality of clinical diagnostic research.

Imposter syndrome develops when high-achieving individuals, despite external measurements of achievement, have a chronic sense of self-doubt paired with a fear of being exposed as a hoax. This endangers one's mental health and well-being. The objective of the study was to determine the prevalence and severity of imposter syndrome among postgraduate residents and to identify the risk factors associated with imposter syndrome. ⋯ Imposter syndrome is a prevalent phenomenon among the residents of Pakistan. Efforts to identify and establish a proper relationship between general demographics and imposter syndrome are required for the healthy work experience of the trainees.

In this paper, we highlight the prevalent misconception among patients regarding the normal value of left ventricular ejection fraction in cardiac function assessment. This misconception arises from the proportion dominance effect, wherein individuals tend to judge based on proportions rather than absolute values. ⋯ To address this, the concept of "Left Ventricular Ejection Fraction - Proportion of Normal" is introduced, which adjusts left ventricular ejection fraction to a patient-specific normal range. This patient-centric approach aims to enhance comprehension, engagement, and adherence by conveying accurate information through the lens of proportions, thereby potentially improving clinical outcomes.

The utilization of postdilatation in primary percutaneous coronary intervention (PCI) is feared to induce suboptimal coronary blood flow and compromise the outcome of the patients. This meta-analysis sought to verify whether postdilatation during primary PCI is associated with worse angiographic or long-term clinical outcomes. ⋯ Postdilatation after stent deployment during primary PCI appears to be associated with an increased risk of no-reflow phenomenon after the procedure. Nevertheless, postdilatation strategy has demonstrated a significant reduction in MACE over the course of long-term follow-up. Specifically, postdilatation significantly decreased the occurrence of TVR. Key messages: What is already known on this topic? Optimizing stent deployment by performing postdilatation during percutaneous coronary intervention (PCI) is essential for long-term clinical outcomes. However, its application during primary PCI is controversial due to the fact that it may provoke distal embolization and worsen coronary blood flow. What this study adds? In this systematic review and meta-analysis of 10 studies, we confirm that postdilatation during primary PCI is associated with worse coronary blood flow immediately following the procedure. On the contrary, this intervention proves advantageous in improving long-term clinical outcomes, particularly in reducing target vessel revascularization. How this study might affect research, practice, or policy? Given the mixed impact of postdilatation during primary PCI, this strategy should only be applied selectively. Future research should focus on identifying patients who may benefit from such strategy.
