Are post-docetaxel treatments effective in patients with castration-resistant prostate cancer and performance of 2? A meta-analysis of published trials.

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
backgroundAbout 20% of patients with prostate cancer have an ECOG performance status (PS) 2 at diagnosis. We investigate if current treatment options for castration-resistant prostate cancer (CRPC) may decrease the risk of death even in patients with ECOG PS of 2.
methodsPubMed was reviewed for phase III randomized trials in patients with CRPC progressed after docetaxel chemotherapy. Characteristics of each study and the relative hazard ratio (HR) for overall survival and 95% confidence interval (CI) were collected. Summary HR was calculated using random- or fixed-effects models depending on the heterogeneity of included studies.
resultsA total of 3,149 patients was available for meta-analysis. In the overall population, the experimental treatments decrease the risk of death by 31% (HR=0.69; 95% CI: 0.63-0.76; P<0.001). The activity of experimental treatments was similar in 2,859 patients with ECOG-PS=0 or 1 with a reduced risk of death of 31% (HR=0.69; 95% CI: 0.62-0.76). A total of 290 patients (9.2%) had ECOG-PS=2 and experimental treatments decreased the risk of death by 26% (HR=0.74; 95% CI: 0.56-0.98; P=0.035) compared with the controls even in this sub-group. When patients were stratified by type of treatment, the reduction of the risk of death was confirmed for hormonal therapies: abiraterone and enzalutamide (HR=0.72; 95% CI: 0.52-0.99; P=0.046), but not for chemotherapy (HR=0.81; 95% CI: 0.48-1.37; P=0.43).
conclusionsWe believe this is the first study reporting a benefit in second-line setting for CRPC patients previously treated with docetaxel and poor PS.
