A study of individual and market level factors to estimate key determinants of financial success among solopreneurs.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
This study investigates how personality traits, age, risk propensity, and structural factors influence the long-term financial success of solopreneurs, defined as solo-founded ventures typically characterized by the absence of a dedicated workforce during the early years of operation. Using data from 4,470 solo-founded ventures in the German Institute for Employment Research/Centre for European Economic Research start-up panel, we model sustained profitability over the first 7 years as a binary outcome and test seven hypotheses grounded in trait, decision-making, and resource-based theories. The regression results show that two psychological traits - Openness and Conscientiousness - significantly increase the likelihood of long-term profitability (odds ratio OR = 1.616; OR = 1.279). Preference for low-risk projects (OR = 1.607) and being age ≤ 50 years (OR = 2.126) further enhance success odds. Conversely, general risk attitude, gender, sector affiliation, and research and development involvement show no significant effects. The results challenge assumptions about sectoral or innovation-based advantages and emphasize the significance of psychological variables in solopreneurship. This study contributes to a multidimensional understanding of entrepreneurial success and supports the development of evidence-based support strategies tailored to individual trait-context combinations.
