PubHealth.info® (a subsidiary of PakMed) presents scientific information mainly based on abstracts of articles published on a variety of public health issues/topics, particularly encompassing population planning, disease prevention, maternal and child health, and communicable and non-communicable diseases (like HIV AIDS, malaria, etc) that are affecting a significant portion of population in developing and developed countries. Here you can find abstracts of articles published on a variety of public health topics under category "Contraception (Birth Control) and Family Planning". Contraception (birth control) is a regimen of one or more actions, devices, or medications followed in order to deliberately prevent or reduce the likelihood of a woman becoming pregnant or giving birth. Therefore contraception is the utilization of various and sundry surgical procedures, devices, practices, agents, or drugs with the intention of preventing conception or impregnation (pregnancy). Methods and intentions typically termed birth control may be considered a pivotal ingredient to family planning. Birth control is a controversial political and ethical issue in many cultures and religions, and although it is generally less controversial than abortion specifically.

ABSTRACT

Suissa and colleagues used logistic regression with splines to reanalyze Transnational Study data on the risk of

venous thromboembolism associated with different types of oral contraceptives (OCs) and concluded that this risk is

equal in first-time users of second- and third-generation formulations. The authors of this letter contend that Swissa

et al.'s models do not fit the data adequately and use World Health Organization data to demonstrate the impact of

correct and incorrect model specification. In the authors' reanalysis of the Transnational Study data, the higher

thromboembolism risks associated with third- versus second-generation OCs persist, particularly in the first year of

use. The correct model to reflect the increase in risk with new users requires an additional parameter to distinguish

OC users from nonusers. For both OC types, the unconstrained spline provides a more convincing approximation to

the step function than the continuity constraint imposed by Suissa. (PubHealth.info Document ID: CONT2T 3-06)
