Conclusions This study confirms known risk factors for PTB and SGA, along with a new variable of interest, financial strain. (springer.com)
Our primary aim was therefore to explore ethno-specific risk factors for PTB and SGA, in particular in relation to psychosocial health, within an urban, multi-ethnic, socially disadvantaged cohort. (springer.com)
We therefore present a comprehensive study of risk factors associated with progression through hospital to either discharge or death, via ICU or not, while accounting for competing risks. (biomedcentral.com)
