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

backgroundSerial symptom assessments using patient-reported outcomes may be challenging to implement in routine clinical practices. We aimed to determine if a single measurement of symptom burden at the time of metastatic diagnosis is associated with survival.

methodsWe examined baseline patient-reported outcomes (within 90 days of diagnosis) of patients newly diagnosed with metastatic breast, lung, colorectal, or prostate cancer using the revised Edmonton Symptom Assessment System (ESASr) questionnaire. The ESASr was categorized into physical, psychological, and total symptom domains whereby scores were classified as none to mild (0-3) or moderate to severe (4-10). Multivariable Cox proportional hazards models were constructed to evaluate the effect of baseline symptom scores on overall survival.

resultsWe identified 1316 patients eligible for analysis. There were 181, 601, 240, and 294 patients with breast, lung, colorectal, and prostate cancer, respectively. Approximately one-quarter of all patients reported moderate to severe physical, psychological, and total symptom subscores. On multivariable Cox regression analysis, older age (P < 0.001), male sex (P = 0.002), primary lung cancer (P < 0.001), and smoking in the previous month (P = 0.007) were predictive of inferior overall survival as were baseline moderate to severe physical (hazard ratio, 1.49; 95% confidence interval, 1.16-1.90; P = 0.002) and total symptom subscores (hazard ratio, 1.38; 95% confidence interval, 1.06-1.81; P = 0.017).

conclusionsA single assessment of baseline symptom burden using the ESASr in patients with metastatic cancer has significant prognostic value. This may represent a feasible first step towards routine collection of patient-reported outcomes in real-world settings where serial symptom measurements can be challenging to implement.
