Case-Control Studies

Comparison of meta-RR of non-Hodgkin lymphoma when using higher exposures to benzene versus all exposures. Meta-RR=meta-analysis relative risk.
Background: Non-Hodgkin lymphoma comprises a heterogeneous group of cancers with unresolved aetiology, although risk factors include environmental exposures to toxic chemicals. Although the ubiquitous pollutant benzene is an established leukemogen, its potential to cause non-Hodgkin lymphoma has been widely debated. We aimed to examine the potential link between benzene exposure and risk of non-Hodgkin lymphoma in humans by evaluating a wide array of cohort and case-control studies using electronic systematic review.
Background: The prevalence of landscape fires has increased, particularly in low-income and middle-income countries (LMICs). We aimed to assess the impact of exposure to landscape fire smoke (LFS) on the health of children. Methods: We conducted a sibling-matched case-control study and selected 552 155 children (aged
Background: Self-harm is a leading cause of morbidity in prisoners. Although a wide range of risk factors for self-harm in prisoners has been identified, the strength and consistency of effect sizes is uncertain. We aimed to synthesise evidence and assess the risk factors associated with self-harm inside prison.

We investigated emotional regulation of autobiographical memories in Alzheimer's disease (AD). AD patients and control participants were asked to retrieve memories in response to “happy” and “sad” cues. Participants were also asked to rate the emotional valence of memories at retrieval as well as at the moment the events were encoded. Results showed that both control participants and AD patients rated memories cued by “happy” as more positive when retrieved than when encoded.
