METHODS: Prospective, longitudinal cohort study conducted between October 2012 and October 2013. Thirty-three eyes from 33 patients (20 females, 13 males; mean age = 73 ± 7 years) were included in the study, and underwent phacoemulsification followed by pseudophakic intraocular lens (IOL) implantation. All patients were evaluated with a high-speed Scheimpflug camera (Corvis ST, Oculus, Wetzlar,...

Objective. To evaluate the performance of high-risk human papillomavirus (HPV) DNA testing in urine samples compared to that of cervical sample testing in Northern Thailand. Methods. Paired urine and cervical samples were collected during the follow-up of women with a previous positive HPV test. HPV testing was performed using the Cobas 4800 HPV Test. Linear Array assay was used for genotyping ...

OBJECTIVE To examine, for polio survivors, whether walking with a carbon-fibre reinforced plastic knee-ankle-foot orthosis (carbon KAFO) is more efficient than walking with an ordinary KAFO or without an orthosis. DESIGN Consecutive sample. SETTING Post-polio clinic, University Hospital of Occupational and Environmental Health, Kitakyushu, Fukuoka, Japan. PARTICIPANTS Eleven polio survivo...

Survival times of patients can be compared using rank tests in various experimental setups, including the two-sample case and t h e cnse of paired dnta. Attention is focussed on two frequently occurring complications in medical applications: censoring and tail alternatives. A review is given of the author’s recent work on a new and simple class of censored rank test:. Various models for tail nl...

Graphical and numerical illustrations of the effects of moderate to severe rounding of normal data on the values of test statistics, actual significance level, and power for one-sample t tests and paired t tests. Goodness-of-fit tests confirm that rounded normal data are not normal. Combinatorial computations, simulations, and graphs are made using R. The level of programming, exposition, and s...
