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

Introduction: This systematic review and meta-analysis explored cognitive and affective empathy differences across Dark Triad traits-Narcissism, Machiavellianism, and Psychopathy. Methods: Registered on PROSPERO and following PRISMA guidelines, PubMed, Scopus, Science Direct, ProQuest, and Google Scholar were searched for studies published until June 2024. Risk of bias was evaluated using Egger's test and Rank correlation test, along with risk-of-bias plots (Robvis) for quality assessment. Results: Fourteen studies (N = 5,328) met the inclusion criteria. Meta-analysis showed Narcissism was negatively associated with affective empathy (r= -.134, p<.05) but not significantly linked to cognitive empathy (r= .061, p= .215), while Machiavellianism had a significant negative correlation with both cognitive (r= -.089, p<.05) and affective empathy (r= -.291, p<.0001). Psychopathy demonstrated the strongest negative association with affective empathy (r= -.347, p<.0001). Moderate-to-high heterogeneity was found across all analyses (I Discussion: This review underscores differential empathy profiles across Dark Triad traits, with significant affective empathy deficits in Psychopathy and Machiavellianism and the complex role of cognitive empathy in Narcissism and Machiavellianism. Further research should examine situational and subtype -specific factors influencing empathy in Dark Triad traits to enhance theoretical understanding and inform interventions.
