Survival analysis of patients with stage I non-small-cell lung cancer using clinical and DNA repair pathway expression variables.
Article in Clinical lung cancer, 2013. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundLung cancer is the leading cause of cancer-related mortality. Understanding patient attributes that enhance survival and predict recurrence is necessary to individualize treatment options.
methodsPatients (N = 162) were dichotomized into favorable (n = 101) and unfavorable (n = 61) groups based on survival characteristics. Ku86 and poly(ADP-ribose) polymerase (PARP) expression measures were incorporated into the analyses. LR, Kaplan-Meier analysis, and Cox regression were used to investigate intervariable relationships and survival. Odds ratios (ORs) and hazard ratios (HRs) with 95% confidence intervals (CIs) were used to assess associations.
resultsSex (OR, 0.32; CI-0.14, 0.76), squamous cell carcinoma (SCC) (OR, 0.41; CI-0.17, 0.98), and recurrence (OR, 0.04; CI-0.01, 0.20) confer an unfavorable outcome with area under the receiver operating characteristic curve (Az) = 0.788. Patients with increased tumor grade (OR = 1.84; CI-1.06, 3.19) or increased Ku86 intensity (OR, 2.03; CI-1.08, 3.82) were more likely to be male individuals, and older patients (OR, 1.70; CI-(1.14, 2.52) were more likely to have SCC. Patients older than the median age (HR, 1.86; CI-1.11, 3.12), patients with SCC (HR, 1.78; CI-1.05, 3.01), patients with recurrence (HR, 4.16; CI-2.37, 7.31), and male patients (HR, 2.03; CI-1.20, 3.43) have a higher hazard. None of the DNA repair measures were associated with significant HRs.
conclusionClinical and pathologic factors that enhance and limit survival for patients with stage I NSCLC were quantified. The DNA repair measures showed little association. These findings are important given that certain clinical and pathologic features are related to better long-term survival outcome than others.
