1 · What the graph read from 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.

2 · The registry

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

backgroundLow body mass index (BMI) and low serum albumin levels are suggested indicators of malnutrition and are associated with poor outcomes in cancer patients. Decreasing androgen can alter lipid metabolism, so the prognostic value of BMI may change in metastatic castration-resistant prostate cancer (mCRPC) patients receiving abiraterone. We aimed to delineate the prognostic value of BMI, serum albumin, and BMI and serum albumin (ALB) combined. MATERIALS AND

methodsA post hoc analysis was performed on data from two randomized clinical trials evaluating the efficacy of abiraterone in chemotherapy-pretreated and -naïve mCRPC patients. Survival analysis was conducted using Kaplan-Meier and Cox proportional hazard methods.

resultsA total of 2,205 mCRPC patients were included in this study. Low ALB independently predicted the OS in both cohorts (HR, 1.54; 95%CI, 1.34-1.78 and HR, 1.40; 95%CI, 1.21-1.64, respectively), while low BMI independently predicted the OS only in the post-chemotherapy cohort (HR, 1.30; 95%CI, 1.12-1.50) but not in the pre-chemotherapy cohort (HR, 1.19; 95%CI, 0.98-1.43). By combining BMI (<25 kg/m

conclusionsOur results demonstrate that the combination of BMI and ALB better characterizes the risk groups irrespective of previous chemotherapy. Patients with high BMI but low ALB have higher risk of death than patients with low BMI but high ALB.
