Alternatively, birth-trauma related venous ischemia of the sternocleidomastoid muscle has been postulated to result in benign fibroblastic proliferation of sternocleidomastoid muscle, also known as fibromatosis colli (Fig. 19) [46].
When alternatively the birth process is considered known, this is taken into account by a weighted, non-parametric estimate with weights based on the relative sizes of the relevant birth cohorts.
Alternatively, the birth cohort effect could reflect an increasing exposure during fetal life leading to impaired testicular development, which in adulthood would be reflected by reduced semen quality in line with the suggested Testicular Dysgenesis Syndrome hypothesis.
Alternatively, narrower birth peaks in E. spelaea, relative to M. minimus, may occur because tight synchrony of reproduction reduces losses to predators (e.g., snakes living in caves) through predator satiation or because tight synchrony of reproduction offers energetic benefits from huddling.
Alternatively, your hormonal birth control could be at fault.
Alternatively, women giving birth in different regions may be more likely to have underlying co-morbidities (i.e. hypertension) who are likely to benefit from interventions.
We exploit cross-sectional (103 provinces) and time (10 years) variations of unemployment and take into account possible heterogeneity in social capital and work ethics controlling for workers' region of birth (or, alternatively, for individual fixed effects).
Alternatively, maybe parity and birth spacing are not among the best predictors or determinants of modern postpartum contraception use in family planning.
Even if all of these women would have a planned home birth or, alternatively, if all of them would have a planned hospital birth, the strength of the associations would have changed but the results would have been in the same direction.
