Statistical methods / analysis
The required sample size was calculated using G Power software version 3.17 for sample size calculation (Heinrich Heine Universität; Düsseldorf; Germany), setting a -error probability at 0.05, power (1- ß error probability) at 0.95%, and effective sample size (w) at 0.3. Collected data will statistically analyzed using Statistical Package for Social Sciences (SPSS); computer software version 20 (Chicago, IL, USA). Chi-square test (x2) for qualitative variables, student (t) test for comparison numerical variables to detect the accuracy of the CCR in spot urine sample in prediction of preeclampsia. The Odds ratio, and the relative risk analysis for detection of the possible risks factors for preeclampsia (nulliparity, previous preeclampsia, obesity, hyperlipidemia, twin, and molar pregnancies), and complications associated with preeclampsia (PTL and/or IUGR).

Summary
Brief summary
Background: Preeclampsia is a pregnancy complication, associated with fetal, and maternal morbidity. There is no established test that fulfills all criteria as a good predictor of preeclmpsia. Objectives: This prospective comparative study designed to evaluate the accuracy of calcium-creatinine ratio (CCR) in spot urine sample in prediction of preeclampsia. Study Design: Prospective comparative study.
Patient and methods: The study will include women between 20-40 years old, attending the ante-natal clinic of Ahmadi hospital for ante-natal care during the period from May 2018 till May 2019 after informed consent, and approval of the Obstetrics department .
After complete obstetrical history, clinical examination, the necessary investigations will be done to exclude other conditions affecting urinary calcium/creatinine ratio.
As part of the routine follow-up in the ante-natal clinics, the urine sample taken from the pregnant women for urine albumin assessment, will be used for the assessment of the CCR after informed consent.
Follow–up of the studied women till delivery; women who will develop preeclampsia will constitute the study group, and other normotensive women without preeclampsia will constitute the controls.
