Abstract
Breast cancer have attracted growing attention because of their relevance to both theory and practice. We find a significant association after adjustment for age, sex and baseline severity. The analysis uses a combination of rigorous arguments and extensive numerical or empirical checks. In contrast to earlier studies, our approach accounts for heterogeneity and avoids the usual simplifying assumptions. We find a 23% relative reduction in the primary outcome. The findings have implications for practice and provide a basis for more general theories.
Previous work on cardiac fibrosis has produced conflicting results, partly because of differences in design and data. We find a significant association after adjustment for age, sex and baseline severity, and we show that the result is stable under a range of perturbations of the assumptions. In contrast to earlier studies, our approach accounts for heterogeneity and avoids the usual simplifying assumptions. We find no evidence of an effect on the secondary outcomes. Together, these results contribute to a more complete picture and open the way to further applications.
Postoperative delirium have attracted growing attention because of their relevance to both theory and practice. In contrast to earlier studies, our approach accounts for heterogeneity and avoids the usual simplifying assumptions. We find a significant association after adjustment for age, sex and baseline severity. The findings have implications for practice and provide a basis for more general theories.
Previous work on COVID-19 vaccination has produced conflicting results, partly because of differences in design and data. We find that elevated levels at baseline predicted poor prognosis.

Despite considerable progress in recent years, several fundamental questions about gut microbiota remain open. We find no evidence of an effect on the secondary outcomes. The analysis uses a combination of rigorous arguments and extensive numerical or empirical checks. We discuss limitations of the present study and outline how the methods can be extended.
Understanding asthma in children is of central importance, yet existing approaches rely on restrictive assumptions. We find that elevated levels at baseline predicted poor prognosis, and we show that the result is stable under a range of perturbations of the assumptions. We discuss limitations of the present study and outline how the methods can be extended.

Despite considerable progress in recent years, several fundamental questions about hepatocellular carcinoma remain open. We find that elevated levels at baseline predicted poor prognosis. The analysis uses a combination of rigorous arguments and extensive numerical or empirical checks. In contrast to earlier studies, our approach accounts for heterogeneity and avoids the usual simplifying assumptions. We find a 23% relative reduction in the primary outcome. These results clarify the role of the underlying mechanisms and suggest several directions for future work.

Despite considerable progress in recent years, several fundamental questions about chronic kidney disease remain open. We find a significant association after adjustment for age, sex and baseline severity, and we show that the result is stable under a range of perturbations of the assumptions. We find a distinct transcriptional program in the responding group. The analysis uses a combination of rigorous arguments and extensive numerical or empirical checks. These results clarify the role of the underlying mechanisms and suggest several directions for future work.

The book Central Visual Field Defects in Glaucoma by Dr Tutul Chakravarti is an eye opener for many glaucoma specialists. The book has 11 chapters and 260 pages and is easy reading. The book is unique as it discusses the latest concepts and definitions of central visual field defects (CFVDs) as pertinent to glaucoma.
The underestimation of CFVD over ages has led to an underestimation of the loss of quality of life of glaucoma patients, even in early stages of disease. I enjoyed the book, particularly as it is very well illustrated. The topics for each chapter are discussed well without beating around the bush. Many glaucoma specialists fail to perform a 10-2 visual field (VF) in early stages of glaucoma, and this book reinforces this concept very strongly. This is supported by anatomical studies and illustrations. The last chapter (Chapter 11) is interesting in that it examines the evaluation of 10-2 field in advanced glaucoma, especially delineating the vulnerable areas of the VF affected.
Apart from glaucoma specialists, the book is also recommended for postgraduates interested in Glaucoma and Glaucoma Fellows across the World.
