The introduction and discussion sections of the 17 systematic reviews and meta-analyses we reviewed indicate that all were intended to assess the diagnostic accuracy and utility of depression questionnaires for the purpose of screening that is, for identification of new cases.
We know of only one study, which was not included in any of the systematic reviews or meta-analyses that we reviewed, that assessed the yield of screening for depression with and without excluding patients with psychiatric disorders already treated with psychotropic drugs.
Since that the significance of many findings in crude analyses was lost in adjusted analyses, we carefully reviewed generalised estimating equation models to identify patterns in covariates significantly associated with both child marriage (table 1) and significantly associated with outcome variables in the adjusted models.
Our study has three main strengths: 1) we used LexisNexis Academic, the largest and most comprehensive database for published news articles; 2) we developed search algorithms that can be replicated in future analyses; and 3) we reviewed the full text of all 32,938 articles to determine their eligibility for inclusion, as opposed to determining eligibility based only on examining article titles.
The other meta-analyses and studies we reviewed were designed to assess the impact on perinatal outcomes of antenatal administration of folic acid.
In the summer of 2007, after all statistical analyses had been completed, we reviewed the distribution of parasite densities and found an unexpected bimodality.
To better inform the future conduct of cost-utility analyses in paediatric populations, we reviewed the published literature reporting utilities among children and adults across selected conditions common to paediatric and adult populations.
Two previous reviews in 1997 and 2002 analysed the same journals we reviewed and found the method of randomisation was unclear in 54% and 34% of trials, respectively.
We reviewed economic analyses of NSCLC therapies published between 2004 and 2014.
In June 2014, we reviewed economic analyses of therapies for NSCLC identified by a MEDLINE, CRD, and HEED database search, using a disease-specific medical subject heading term ("lung neoplasms") and subheading ("economics").
