Comparing Clinical and Economic Outcomes Associated with Early Initiation of Combination Therapy of an Alpha Blocker and Dutasteride or Finasteride in Men with Benign Prostatic Hyperplasia in the United States.
Article in Journal of managed care & specialty pharmacy, 2016. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers, 1 of them a synthesis that pooled it.
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
backgroundBenign prostatic hyperplasia (BPH) is a common disease in men that is characterized by lower urinary tract symptoms. Pharmacologic treatment with alpha blockers (ABs) and 5-alpha reductase inhibitors (5ARIs) is recommended to alleviate symptoms, prevent disease progression that can lead to complications, and reduce health care costs.
objectiveTo compare clinical, economic, and health care resource utilization outcomes among BPH patients treated with early continuous combination AB and 5ARI therapy (dutasteride vs. finasteride) using administrative claims data from the United States.
methodsA retrospective analysis of administrative claims data from 2003-2013 was conducted to compare outcomes between patients with claims for early combination therapy with dutasteride + AB and patients with claims for early finasteride + AB. The study population included males aged older than 50 years with at least 1 medical claim with a diagnosis of BPH and pharmacy dispensing for AB and 5ARI therapies. Outcomes included acute urinary retention (AUR), prostate-related surgery, clinical progression, medical and pharmacy costs, and health care resource utilization. Inverse probability of treatment (IPT) weighted Cox proportional hazards, linear, and Poisson regression models were used to assess the association between outcomes and early combination therapy as appropriate.
resultsA total of 2,778 patients were included in the early finasteride + AB treatment cohort, and 4,125 patients were included in the early dutasteride + AB cohort. Dutasteride users were younger than finasteride users (mean age: 64.8 vs. 67.5 years, P < 0.001) and had a greater mean number of urologist visits (10.7 vs. 7.9, P < 0.001) during baseline. After adjusting for confounding using IPT weighting, no statistically significant difference was observed between dutasteride and finasteride for AUR (hazard ratio [HR] = 0.845, 95% CI = 0.660-1.070, P = 0.1643), prostate-related surgery (HR = 0.806, 95% CI = 0.568-1.171, P = 0.2525), and clinical progression (HR = 0.834, 95% CI = 0.663-1.043, P = 0.1122). While dutasteride was associated with higher pharmacy costs per month (adjusted monthly cost difference = $79, 95% CI = $45-$105), total all-cause medical costs were not significantly different between the 2 cohorts (adjusted monthly cost difference = -$44, 95% CI = -$110-$22).
conclusionsClinical and economic outcomes were similar between the early dutasteride + AB and early finasteride + AB cohorts, with no statistically significant differences detected.
