Contemporary Clinical Trials
|January 10, 2023
Summary
Women comprised 30% of first authors in Indian randomized controlled trials (RCTs) from 2011-2020, with no significant change over time. This highlights persistent gender disparity in clinical trial leadership, necessitating increased efforts for women
Area of Science:
- Clinical Trials Research
- Gender Studies in Medicine
- Public Health Policy
Background:
- Trial leadership significantly influences study conduct.
- Gender composition of Indian randomized controlled trial (RCT) leadership remains unquantified.
- This study addresses the gap in understanding gender representation in Indian RCTs.
Purpose of the Study:
- To quantify the gender composition of first authors of RCTs published from India.
- To analyze gender distribution trends in RCT leadership over a decade (2011-2020).
Main Methods:
- A systematic search of the PubMed database was conducted using the keyword "randomized controlled trial".
- Studies included were classified as RCTs, with first author affiliation in India, published between 2011 and 2020.
- First author gender was determined using Gender-API and manual verification.
Main Results:
- A total of 4136 RCTs were analyzed, with gender identified for 4056 (98%) first authors.
- Women constituted 30% (1198) and men 70% (2858) of identified first authors.
- No significant change in gender distribution was observed over the ten-year period (P = 0.78).
Conclusions:
- Gender disparity persists in the leadership of RCTs originating from India.
- Current gender distribution in RCT leadership requires significant improvement.
- Greater efforts are needed to promote the inclusion of women as leaders in clinical trials.

Sex-linked Disorders
102.6K
Like autosomes, sex chromosomes contain a variety of genes necessary for normal body function. When a mutation in one of these genes results in biological deficits, the disorder is considered sex-linked.

Bias in Epidemiological Studies
484
Biases can arise at various stages of research, from study design and data collection to analysis and interpretation. Recognizing and addressing these biases is essential to ensure the validity and reliability of epidemiological findings.Broadly speaking, biases in epidemiology fall into three main categories: selection bias, information bias, and confounding. A more detailed description of possible biases is:

X-linked Traits
55.1K
In most mammalian species, females have two X sex chromosomes and males have an X and Y. As a result, mutations on the X chromosome in females may be masked by the presence of a normal allele on the second X. In contrast, a mutation on the X chromosome in males more often causes observable biological defects, as there is no normal X to compensate. Trait variations arising from mutations on the X chromosome are called “X-linked”.

Randomized Experiments
7.1K
The randomization process involves assigning study participants randomly to experimental or control groups based on their probability of being equally assigned. Randomization is meant to eliminate selection bias and balance known and unknown confounding factors so that the control group is similar to the treatment group as much as possible. A computer program and a random number generator can be used to assign participants to groups in a way that minimizes bias.

Nondisjunction
76.0K
During meiosis, chromosomes occasionally separate improperly. This occurs due to failure of homologous chromosome separation during meiosis I or failed sister chromatid separation during meiosis II. In some species, notably plants, nondisjunction can result in an organism with an entire additional set of chromosomes, which is called polyploidy. In humans, nondisjunction can occur during male or female gametogenesis and the resulting gametes possess one too many or one too few chromosomes.

Nature and Nurture
20.6K
Many human characteristics, like height, are shaped by both nature—in other words, by our genes—and by nurture, or our environment. For example, chronic stress during childhood inhibits the production of growth hormones and consequently reduces bone growth and height. Scientists estimate that 70-90% of variation in height is due to genetic differences among individuals, and 10-30% of variation in height is due to differences in the environments that individuals experience,...
