Introction
1 State the marker examined, the study objectives, and any prespecified hypotheses.
Materials and methods
Patients
2 Describe the characteristics (e.g. disease stage or comorbidities) of the study patients, including their
source and inclusion and exclusion criteria.
3 Describe treatments received and how chosen (e.g. randomized or rule-based).
Specimen characteristics
4 Describe type of biological material used (including control samples) and methods of preservation
and storage.
Assay methods
5 Specify the assay method used and provide (or reference) a detailed protocol, including specific
reagents or kits used, quality control proceres, reprocibility assessments, quantitation methods,
and scoring and reporting protocols. Specify whether and how assays were performed blinded to the
study endpoint.
Study design
6 State the method of case selection, including whether prospective or retrospective and whether
stratification or matching (e.g. by stage of disease or age) was used. Specify the time period from
which cases were taken, the end of the follow-up period, and the median follow-up time.
7 Precisely define all clinical endpoints examined.
8 List all candidate variables initially examined or considered for inclusion in models.
9 Give rationale for sample size; if the study was designed to detect a specified effect size, give the
target power and effect size.
Statistical analysis methods
10 Specify all statistical methods, including details of any variable selection proceres and other
model-building issues, how model assumptions were verified, and how missing data were handled.
11 Clarify how marker values were handled in the analyses; if relevant, describe methods used for
cutpoint determination.
Results
Data
12 Describe the flow of patients through the study, including the number of patients included in each
stage of the analysis (a diagram may be helpful) and reasons for dropout. Specifically, both overall
and for each subgroup extensively examined report the numbers of patients and the number of
events.
13 Report distributions of basic demographic characteristics (at least age and sex), standard (disease-specific) prognostic variables, and tumor marker, including numbers of missing values.
Analysis and presentation
14 Show the relation of the marker to standard prognostic variables.
15 Present univariate analyses showing the relation between the marker and outcome, with the
estimated effect (e.g. hazard ratio and survival probability). Preferably provide similar analyses for
all other variables being analyzed. For the effect of a tumor marker on a time-to-event outcome, a
Kaplan–Meier plot is recommended.
16 For key multivariable analyses, report estimated effects (e.g. hazard ratio) with confidence intervals
for the marker and, at least for the final model, all other variables in the model.
17 Among reported results, provide estimated effects with confidence intervals from an analysis in which
the marker and standard prognostic variables are included, regardless of their statistical significance.
18 If done, report results of further investigations, such as checking assumptions, sensitivity analyses,
and internal validation.
Discussion
19 Interpret the results in the context of the prespecified hypotheses and other relevant studies; include
a discussion of limitations of the study.
20 Discuss implications for future research and clinical value.
