Efficacy and safety of robotic spine surgery: systematic review and meta-analysis.

Background: Robotic surgery (RS) may offer benefits compared with freehand/conventional surgery (FS) in the treatment of patients with spinal disease. The aim of this study was to evaluate the efficacy and safety of RS versus FS in spinal fusion.

Methods: A systematic review and meta-analysis was performed.

Mammography use and factors associated with its use after the introduction of breast cancer screening programmes in Spain.

The aim of this study was to measure the use of mammography and the factors associated with testing among Spanish women, after the introduction of screening programmes in Spain. We conducted a cross-sectional population survey of a representative sample of women aged 40-70 (2409 women). Data collection took place in October 2000, using a questionnaire addressing the dependent variable (mammography use) and the independent variables (socio-demographic and socio-health factors, and women's knowledge and attitudes).

[Differences in the factors related to the use of mammograms among Spanish women in 1994 and 2000].

Background: The screening mammography is the most highly effective procedure for early breast cancer detection. This study is aimed at ascertaining the differences in the factors related to Spanish women 40-70 years of age having had mammograms in 1994 and 2000 and among those having had at least one mammogram within the two years prior.

Method: Comparison of the results of two surveys conducted in 1994 and 2000, each on samples of women representative of Spanish women 40-70 years of age (3,218 in 1994 and 2,409 in 2000).
