Polypharmacy and comorbidity are associated with a lower early virologic response in hepatitis C patients treated with first generation protease inhibitor triple therapy: a preliminary analysis.

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
BACKGROUND AND
aimsThe protease inhibitors (PIs) boceprevir and telaprevir are currently standard treatment as part of triple therapy regimens (TTx) for chronic HCV genotype 1 (GT1) patients. In this preliminary analysis, we have compared demographic variables, polypharmacy, and Charlson's comorbid index (CCI) with Rapid Virological Response (RVR) and extended RVR (eRVR) rates in HCV GT1 patients receiving PI containing TTx.
methodsRetrospective descriptive cohort study.
resultsAmong 74 HCV patients (46 M, 28 F; age: 54.43 ± 9.52 years; African Americans: 59.5 %) in this initial analysis, 44 % achieved RVR. All these RVR patients also achieved eRVR. Patients achieving RVR and eRVR were 50 ± 11.7 (mean ± SD) years old, compared to 58 ± 5.2 years without an RVR (p < 0.005). The average number of medications taken by patients achieving RVR and eRVR was 5 ± 2.7 compared to 9.24 ± 3.4 in patients not achieving RVR and eRVR (p < 0.005). Twenty-five percent of patients who were not on CYP3A4 inhibitors had an RVR and eRVR compared to 63.2 % who were taking CYP3A4 inhibitors (p = 0.001). Patients achieving RVR and eRVR had a lower CCI (1.61 ± 1.37) compared to those not achieving RVR and eRVR (2.8 ± 2.7; p = 0.02). Multivariate analysis also revealed a significant correlation between increased polypharmacy and CCI with lower RVR and eRVR rates.
conclusionsThese preliminary treatment data demonstrate that increased polypharmacy and higher degrees of comorbidity decrease RVR and eRVR rates among patients receiving first generation PI-containing TTx regimens.
