Overview

What is he best known for?

The fields of study he is best known for:

  • Internal medicine
  • Statistics
  • Cancer

Niels Keiding spends much of his time researching Gynecology, Internal medicine, Semen quality, Econometrics and Semen. His Gynecology research integrates issues from Cancer, Levonorgestrel, Cohort study and Obstetrics. Niels Keiding interconnects Endocrinology and Oncology in the investigation of issues within Internal medicine.

Niels Keiding has researched Semen quality in several fields, including Hypospadias, Incidence, Testicular cancer and Reproductive health. His Hypospadias research includes elements of Physiology and Genitourinary system. His Semen research includes elements of Sperm and Infertility.

His most cited work include:

  • Statistical Models Based on Counting Processes. (2513 citations)
  • Evidence for decreasing quality of semen during past 50 years. (2135 citations)
  • Male reproductive health and environmental xenoestrogens (1285 citations)

What are the main themes of his work throughout his whole career to date?

Demography, Statistics, Internal medicine, Survival analysis and Econometrics are his primary areas of study. His biological study spans a wide range of topics, including Fertility, Danish, Epidemiology, Cohort study and Gerontology. His Fertility research focuses on Gynecology and how it relates to Semen quality and Obstetrics.

His research in Internal medicine intersects with topics in Endocrinology and Oncology. As part of his studies on Survival analysis, Niels Keiding often connects relevant areas like Proportional hazards model. His research integrates issues of Regression analysis, Statistical model and Regression in his study of Econometrics.

He most often published in these fields:

  • Demography (21.77%)
  • Statistics (16.46%)
  • Internal medicine (15.70%)

What were the highlights of his more recent work (between 2008-2021)?

  • Demography (21.77%)
  • Statistics (16.46%)
  • Survival analysis (12.41%)

In recent papers he was focusing on the following fields of study:

His primary areas of study are Demography, Statistics, Survival analysis, Fertility and Econometrics. His Demography study incorporates themes from Parity, Infertility, Gynecology, Cohort and Birth rate. Niels Keiding has included themes like Proportional hazards model, Time to pregnancy and Censoring in his Survival analysis study.

His Fertility research integrates issues from Fecundity, Danish and Abortion. His Econometrics research is multidisciplinary, incorporating elements of Observational study, Markov process, Renewal theory, Regression analysis and Sample. The various areas that Niels Keiding examines in his Hazard ratio study include Incidence and Obstetrics.

Between 2008 and 2021, his most popular works were:

  • Thrombotic Stroke and Myocardial Infarction with Hormonal Contraception (340 citations)
  • Thrombotic Stroke and Myocardial Infarction With Hormonal Contraception (260 citations)
  • Interpretability and importance of functionals in competing risks and multistate models (134 citations)

In his most recent research, the most cited papers focused on:

  • Internal medicine
  • Statistics
  • Cancer

His primary scientific interests are in Internal medicine, Econometrics, Regression analysis, Cohort study and Hormone therapy. Many of his research projects under Internal medicine are closely connected to THROMBOTIC STROKE with THROMBOTIC STROKE, tying the diverse disciplines of science together. His work deals with themes such as Interpretability, Unmeasured confounding, External validity and Regression, which intersect with Econometrics.

Statistics covers Niels Keiding research in Regression analysis. His Survival analysis research focuses on subjects like Censoring, which are linked to Competing risks. His work carried out in the field of Epidemiology brings together such families of science as Fertility and Gynecology.
