Levels and Predictors of Knowledge, Attitudes, and Practices Regarding Contraception Among Female TV Studies Undergraduates in Nigeria: Cross-Sectional Study

Levels and Predictors of Knowledge, Attitudes, and Practices Regarding Contraception Among Female TV Studies Undergraduates in Nigeria: Cross-Sectional Study

The study population was female students of NTA TV College who gave their consent to participate in the study. Female students of NTA TV College who withdrew their consent to participate at any stage of the study and those who were not available for one reason or the other during the research were excluded from the study.

Improving Access to and Delivery of Maternal Health Care Services to Prevent Postpartum Hemorrhage in Selected States in Nigeria: Human-Centered Design Study

Improving Access to and Delivery of Maternal Health Care Services to Prevent Postpartum Hemorrhage in Selected States in Nigeria: Human-Centered Design Study

Roughly 31% of female deaths in Nigeria are attributed to maternal causes, and in 2018, the country recorded a maternal mortality ratio of 512 maternal deaths per 100,000 live births [9]. Some factors contributing to this sad reality include poor access to essential medicines, including uterotonics for PPH management, and inadequate health care providers [10].

Predicting Transvaginal Surgical Mesh Exposure Outcomes Using an Integrated Dataset of Blood Cytokine Levels and Medical Record Data: Machine Learning Approach

Predicting Transvaginal Surgical Mesh Exposure Outcomes Using an Integrated Dataset of Blood Cytokine Levels and Medical Record Data: Machine Learning Approach

A cohort of 20 healthy, nonpregnant female patients, divided evenly between the 2 categories, was determined necessary for statistical observation of a difference in blood cytokine biomarkers with a 10% chance of error. Briefly, this statistical analysis used a 1-tailed t test based on a priori power analysis, a Cohen d of 1, and a conservative study power of 0.80.

Assessing the Data Quality Dimensions of Partial and Complete Mastectomy Cohorts in the All of Us Research Program: Cross-Sectional Study

Assessing the Data Quality Dimensions of Partial and Complete Mastectomy Cohorts in the All of Us Research Program: Cross-Sectional Study

Additionally, we restricted the phenotype to the earliest occurrence of a procedure and to female participants who were at least 18 years or older at the time of the procedure. We developed a data quality dimensions (DQD) framework and evaluation matrix that was adapted from Kahn et al [16].

Net Reproduction Number as a Real-Time Metric of Population Reproducibility

Net Reproduction Number as a Real-Time Metric of Population Reproducibility

However, this cohort-based measure is biased when there is male-to-female sex-ratio imbalance at birth [2,3]. The TFR does not account for mortality rates among childbearing-age women, possibly affecting population reproducibility [2,4]. These limitations reduce TFR’s ability to accurately reflect a country’s population replacement dynamics.

Reliable Web-Based Auditory Cognitive Testing: Observational Study

Reliable Web-Based Auditory Cognitive Testing: Observational Study

The sample included 75 female and 47 male participants. As these participants did not have pure-tone audiometry performed, we were unable to grade the severity of hearing loss like for the in-person participants. Age in the in-person (n=153; green) versus web-based (n=58; yellow) cohort of participants. People older than 70 years of age were less likely to participate in web-based auditory cognitive experimentation.

Development and Validation of a Machine Learning–Based Early Warning Model for Lichenoid Vulvar Disease: Prediction Model Development Study

Development and Validation of a Machine Learning–Based Early Warning Model for Lichenoid Vulvar Disease: Prediction Model Development Study

The study incorporated 2634 female patients who attended the West China Second Hospital of Sichuan University from January 2013 to December 2017. Based on the results of their medical examinations, these patients were divided into 2 groups, that is, the normal vulvovagina group (group 0) consisting of 1080 cases and the LVD group (group 1) comprising 1554 cases.

Integrating Real-Time Air Quality Monitoring, Ecological Momentary Assessment, and Spirometry to Evaluate Asthma Symptoms: Usability Study

Integrating Real-Time Air Quality Monitoring, Ecological Momentary Assessment, and Spirometry to Evaluate Asthma Symptoms: Usability Study

Participants (N=40) were primarily female (n=36, 90%), college graduates (n=25, 66%), employed (n=30, 75%), owners of their home (n=27, 67.5%), and residing in a single-family home (n=30, 75%), and they were from 18 (36%) different US states. Most participants indicated they were non-Hispanic (n=38, 95%) and White (n=26, 67%). A total of 5 (13%) participants indicated Black or African American race, 4 (10%) reported their race as American Indian or Alaskan Native, and 2 (5%) indicated Asian race.
