Format

A data frame of 304 observations and 29 variables:

	name	a unique data set identifier; use this to access data sets for analysis
	Journal	the publishing journal
	PubMedID	the publication PubMed identifier
	TrialRegistration	trial registration identifier, if applicable; for example, the ClinicalTrials.gov identifier (NCT number) or other
	Title	publication title
	Year	publication year
	ClinicalTrial	unique clinical trial identifier; note that ClinicalTrial and Figure are joined to create the unique trial-figure identifier, name
	Figure	figure identifier; note that ClinicalTrial and Figure are joined to create the unique trial-figure identifier, name
	Cancer	study cancer type
	Subgroups	subgroups studied, if any
	ReportedSampleSize	overall study sample size
	RandomizationRatio	the ratio of patients randomized to each study arm
	RandomizationType	treatment characteristic by which patients were randomized, e.g., patients randomized to receive different dose levels, durations or timing of therapy, or therapy agent
	TrialDesign	trial design, i.e., superiority, inferiority, or both
	Metastatic	indicator of metastatic or non-metastatic cancer
	InterventionClass	the class of drug/treatment used in the intervention/treatment arm
	Outcome	the outcome or event for each data set, e.g., OS, PFS, DFS, etc.
	PrimaryStudyResults	the primary outcome results, either positive, negative, or mixed (i.e., co-primary endpoints with both positive and negative outcomes)
	Units	the time units for Outcome, e.g., days, weeks, months, years
	HazardRatio	the reported/published hazard ratio for Outcome
	Arms	the two treatment arms for each data set
	NumberofArms	the number of treatment arms for the entire study (note that data sets in this package have two arms each)
	qsAtRisk	quality score for at-risk tables (0-3)
	qsTotalEvents	quality score total events (0-3)
	qsHazardRatio	quality score for hazard ratio (0-3)
	qsMedian	quality score for median time-to-event (0-3)
	QualityScore	aggregate quality score for each figure over the four metrics (hazard ratio, total events, median time-to-event, number at-risk) comparing published to re-capitulated data
	QualityMax	maximum quality score possible for each figure; each quality metric can be score from 0 (worst) to 3 (best); the maximum score possible for each figure depends on the number of metrics reported by the publication
	QualityPercent	a quality score percentage for each figure, from 0 (worst) to 100 (best): QualityScore / QualityMax * 100
