Most studies reported baseline patient characteristics, including average age and gender (65 and 58.8 % of studies, respectively), while symptoms of ADPKD frequently reported at baseline included hypertension and proteinuria (21.3 and 10.6 % studies, respectively).
However, the EHR did not encourage most students to use online resources beyond their reported baseline levels.
We chose age for two reasons: first, it is a commonly reported baseline characteristic and, second, is the most likely common confounder across different disease groups.
Most CT screening studies report baseline rates of 14 43% of non-calcified nodules (5 10 mm in diameter); this relatively large range is attributed to geographic differences in nodule prevalence and the slice thickness used (Diederich et al, 2002; Wilson et al, 2008).
However, other items were reported poorly; most concerning was the limited number of RCTs reporting baseline PROs (n = 13, 36%), or reporting approaches for dealing with missing PRO data (n = 14, 39%) (Fig. 2).
Rather than combine all 5 years of the Nationwide Inpatient Sample, we report baseline characteristics for 1997, the most recent year for which these data are available.
Cerebral oximetry may be a valuable monitor, but few validation data are available, and most report the change from baseline rather than absolute accuracy, which may be affected by individuals whose oximetric values are outside the expected range.
Furthermore, investigators should report baseline comparisons on important prognostic variables.
Pain and eating problems among children and parents feeling upset and guilty were the most frequently reported impacts at baseline.
On the MINI the most commonly reported disorders at baseline were current depression (N = 10) and PTSD (N = 14).
