A comparative assessment of active surveillance for localized prostate cancer in the community versus tertiary care referral center.
Observational study in World journal of urology, 2014. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper, 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
objectivesTo date, evidence on active surveillance (AS) is restricted to protocol-based studies. Conversely, practice patterns outside of such protocols are unknown. The aim of this study was to capture the current AS treatment patterns for localized prostate cancer in patients managed by office-based urologists compared to patients treated at a tertiary care center. METHODS AND MATERIALS: Two prospective cohorts were investigated: 361 AS arm patients of the German Hormonal treatment, Active surveillance, Radiation therapy, OP, Watchful waiting (HAROW) study, an observational health service study and 387 protocol-based AS patients treated at the Department of Urology of the Kantonsspital Aarau, Switzerland were included. Observational non-protocol HAROW versus on-protocol Kantonsspital Aarau (KSA) was compared, and active-treatment-free survival represented the primary outcome.
resultsStudy population of the observational HAROW versus tertiary care protocol-based KSA cohorts differed statistically significantly regarding age (p < 0.001) and proportion of patients meeting the Chism criteria (p < 0.001). In stratified analyses, AFTS at 1 and 2 years was, respectively, 87.7 % (95 % CI 84.0-91.7) and 75.0 % (95 % CI 69.7-80.8) in HAROW patients compared to 90.8 % (95 % CI 87.8-93.9) and 75.3 % (95 % CI 70.7-80.1) for patients in the KSA cohort (p = 0.97).
conclusionWe demonstrate significant differences in terms of AS inclusion, surveillance and discontinuation criteria between patients managed by office-based urologists compared to their tertiary care counterparts. Interestingly, the risk of deferred active therapy was equally moderate for both groups in the short-term follow-up.
