    cohorts are an ideal design to relate the historical exposure to infection and development of clinical malaria over time, and analysis methods should consider the longitudinal nature of the data. Models must take into account the acquisition of immunity... the hypothesis that studies often fail to use appropriate statistical methods but that this would improve with the recent increase in accessibility to and expertise in longitudinal data analysis.

    Joint modelling of longitudinal data: a scoping review of methodology and applications for non-time to event data
    (2025-02-17) Ouko R.K.; Mukaka M.; Ohuma E.O.; Ouko R.K.; Mahidol University
    . There is less awareness about the amount of literature available for joint models of non-time-to-event data. Therefore, this review's main objective is to summarise the current state of joint modelling of non-time-to-event longitudinal data. METHODS: We....75%) for the frequentist approach. Most studies used R statistical software (33 studies; 40%) for analysis. CONCLUSION: A wide range of methods for joint-modelling non-time-to-event longitudinal data exist and have been applied to various areas. An exponential increase

    is the angle between the direction of Cerenkov photon and the direction of primary particle) is reconstructed from the image of WFCTA to study the longitudinal development of the shower (similar to dN/dX). In this paper, the dN/dθ reconstructing method...V. The longitudinal development is one of the main tools to distinguish nuclei from each other. WFCTA is composed of 18 imaging air Cerenkov telescopes, each telescope has 32 × 32 pixels, covers a field of view 16o × 16o (each pixel corresponding to 0.5o × 0.5o

    Longitudinal research is the term coined to differentiate the methodology and utility of this type of research with that of cross-sectional research. It is a necessary tool for studying social change and dynamic behavior due to its ability... to track individuals over time to assess change. A prime principle of longitudinal studies is to link individual data across time. The need for and utility of longitudinal research are extremely relevant today. The growing diversity of changes led

    over the course of patient management as part of routine care. METHODS: This prospective, longitudinal, interventional study recruited 28 subjects who were intubated and mechanically ventilated. For a maximum of 7 d and on clinical need for endotracheal...BACKGROUND: Endotracheal suctioning causes discomfort, is associated with adverse effects, and is resource-demanding. An artificial secretion removal method, known as an automated cough, has been developed, which applies rapid, automated deflation

    The Onset of Empty Nest Increases Subjective Well-Being Amongst Middle-Aged and Older Adults: Longitudinal National Evidence From Thailand, 2015–2022
    (2026-03-01) Pengpid S.; Peltzer K.; Satitvipawee P.; Kaewchankha W.; Suanrueang P.; Hajek A.; Pengpid S.; Mahidol University
    to 2022. Methods: The Health, Aging and Retirement in Thailand study's four waves of longitudinal data were used. The pooled analytic sample of individuals with live children consisted of 6535 observations of men and 8521 observations of women from four... established methods. The longitudinal association between the shift to an empty nest and subjective well-being was estimated using linear fixed-effects (FE) regressions. Results: Adjusted FE regressions showed a positive association between the transitions

We examined the four-year longitudinal changes in the ALI using two methods: comparing ALI scores....28) and "One ALI approach"(CR 1.15, 95% CIs: 1.01, 1.32), whereas FWC did not show statistical significance in both methods. Conclusions WFC was longitudinally associated with increased ALI. It is crucial to mitigate the effects of work-to-family conflict. Key
