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

objectiveMetastatic castration-resistant prostate cancer (mCRPC) remains associated with poor long-term outcomes, and survival under current treatment is modest. Prostate-specific membrane antigen (PSMA)-targeted alpha therapy using MATERIALS AND

methodsThis prospective, open-label, single-arm study enrolled 16 patients with progressive mCRPC refractory to standard therapies. Patients received

resultsXerostomia occurred in 75% of patients, predominantly grade-1 (68.8%), with one grade-2 case. Hematologic toxicities were mild-to-moderate: anemia 68.8% (grade 3: 6.3%), leukopenia 25.0% (all grade 1-2). No grade 4 toxicities or treatment-related deaths occurred. Significant laboratory changes included hemoglobin  decrease (117.7 ± 19.2 versus 105.0 ± 19.7 g/L, p = 0 .012). PSA50 response was 37.5% (95% confidence interval [CI]: 15.2%-64.6%), with a median PSA change of 18.1% (range: -143.0% to 100.0%). Radiographic response was 31.3% (95% CI: 11.0-58.7%), and the disease control (partial response + stable disease) rate was 62.5% (95% CI: 35.4-84.8%).
