General characteristics included study design, first author, year of publication, sample size, interventions and various types of artificial total disc replacements (TDRs).
24 25 In the GSA group, we used meta-regression approach within the bivariate model 26 to explore the following studies characteristics as potential sources of heterogeneity in test performance: year of publication, sample size, geographical area, and place of screening.
Extracted data included author names, year of publication, sample source, number of male and female patients, tumor classification system, IHC methodology (antibody source, dilution), and clinical parameters (tumor stage, lymph node metastasis, distant metastasis).
The following information was abstracted: author, year of publication, sample size, disease, type of impairment and disability scales, distinction between generic or disease-specific and mental or physical HRQL, and the associations with impairment.
After adjusting for journal of publication, sample size and funding source, each point increase in PICOT score was significantly associated with a 2.1% increase in the OQS and a 14.2% increase in the KS.
From each study, we extracted a predetermined set of data, including name of the first author, year of publication, sample characteristics, study settings, follow-up details, number of deaths, effect measures, and confounders.
The selective data are authors' names, year of publication, sample size per arm, regimen used, tumour stage, median or mean age of patients, vaccine formulation, information pertaining to study design and main results of clinical efficacy in each arm.
The extracted information included the following items: first author's name; year of publication; sample size; population; gender; treatment arms; usage of PSA; duration of catheter placement; and catheter-related infection outcomes (infection rate, organism analyses).
We included the author's last name, year of publication, sample size, mean subject age, cancer clinical classification, type of PCR method, and other relevant characteristics of the study population.
Full-text articles were further assessed and data were entered into a prespecified table that included information on authors, year of publication, sample size, type of DPP-4 inhibitor, duration of follow-up, comparator drug, baseline HbA1c and outcomes.
