They vary considerably with regard to study design, number of subjects, study duration, and in terms of the saline solutions used, mode of application, and the parameters assessed.
If a symptom occurred more than once in any subject, durations were added, whereas severity was considered to be the maximum of the severity scores.
Over the study duration, subject retention averaged more than 95% on an annual basis (and 98% of living subjects each year) as shown in Fig. 1.
We also did not have information on statin use outside the Veterans Affairs system and therefore could have underestimated some subjects' duration of use.
Towards developing the electrical engineering technology program and designing a curriculum structure in Universiti Teknikal Malaysia Melaka (UTeM), a market survey has been conducted to gather opinion from industries on the relevant subjects, duration of training required and also the career opportunity.
This discrepancy may be due to factors such as biological heterogeneity of the subjects, duration of illness or the antipsychotic medications.
These include descriptors such as reporting of study size, study design, study subjects, duration of follow-up and mention of harm or limitations of the research (Appendix S2).
In our analysis entering all variables and including all subjects, duration of illness (p < 0.001), diagnosis of schizophrenia spectrum disorder (p = 0.003), substance abuse (p = 0.009) and female gender (p = 0.031) were significantly associated with suicide attempt (Table 4).
The innovation of the ORIGIN study over previously mentioned studies was its size (12,537 subjects), duration (median follow-up 6.2 years), and inclusion of a diverse population (including prediabetes and well-controlled diabetic patients).
Logistic problems in early phase of the study, support tools in sending specimens to laboratories in Kuala Lumpur, refusals to participate in the study by potential subjects, duration of study period and refusals for blood to be taken for specimen especially among younger subjects were among the limitations we faced during the study.
