Association of comorbid disease burden at diagnosis with higher tumor grade in men with non-metastatic prostate cancer.
Article in Prostate cancer and prostatic diseases, 2017. 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
backgroundWhile older age is associated with higher tumor grade, it is unknown whether comorbid disease burden has a similar, independent association. We sought to evaluate the impact of comorbid disease burden on tumor grade at diagnosis as indicated by biopsy Gleason score.
methodsWe conducted an observational cohort study of 1260 men newly diagnosed with non-metastatic prostate cancer from 1998 to 2004 at two Veterans Affairs Medical Centers. Multivariable ordinal and multinomial logistic regression were used to evaluate the association between Charlson Comorbidity Index score and biopsy Gleason score.
resultsMen with Charlson scores of 2 (odds ratio (OR) 1.8, P<0.001) and 3+ (OR 1.8, P<0.001) had significantly greater odds of higher Gleason scores, compared with men with Charlson scores of 0. In a multinomial logistic regression model predicting Gleason 7 vs ⩾6, only men with Charlson scores of 2 (OR 1.6, P=0.01) had greater odds of having a Gleason 7 tumor, compared with those with Charlson scores of 0. In a multinomial logistic regression model predicting Gleason 8-10 vs ⩽6, those with Charlson scores of 1 (OR 1.6, P=0.047), 2 (OR 2.8, P=0.01) and 3+ (OR 2.9, P=0.001) had higher odds of having a Gleason 8-10 tumor.
conclusionsModerate-to-heavy comorbid disease burden at diagnosis may be associated with high tumor grade, independent of age, and is a stronger predictor of Gleason 8-10 than Gleason 7 disease.
