Prevalence of Measurable Disease in Metastatic Castration-resistant Prostate Cancer.
Article in Clinical genitourinary cancer, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
backgroundBecause of the low historical prevalence of measurable disease in metastatic castration-resistant prostate cancer (mCRPC), phase II trials have used prostate-specific antigen (PSA) and bone scan changes as primary end points. Frequent whole-body imaging and improved computed tomography technology currently identify measurable disease more frequently, warranting consideration of objective response as a major end point. PATIENTS AND
methodsData from reported phase III trials of mCRPC were analyzed. The proportion of patients with measurable disease, setting (pre-docetaxel [D], D-based, post-D), year of starting accrual, PSA, and the requirement for symptoms were collected. The χ
resultsTwenty phase III trials totaling 19,276 men with mCRPC were evaluable. Three trials (n = 1289) started accruing before 2000 and 17 trials (n = 17,987) accrued after 2000. The proportion of measurable disease rate for all trials was 47.5%. The measurable disease rate was significantly higher (P < .001) in trials that accrued after 2000 versus before 2000 (48.7% vs. 31.1%; P < .001), D-based (51.8%) or post-D patients (48.9%) compared with pre-D patients (38.6%) and in trials allowing symptomatic versus asymptomatic/minimally symptomatic patients (50.1% vs. 40.0%).
conclusionThe proportion of men with measurable disease was significantly higher in phase III trials of mCRPC that accrued after 2000, in D-based or post-D patients and in trials that allowed symptomatic patients. Because of the association of objective measurable changes with survival, Response Evaluation Criteria in Solid Tumors changes might warrant consideration as a major end point in phase II trials to obtain a firm signal of efficacy before launching phase III trials.
