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

background and purposeNon-small cell lung cancer (NSCLC) is the most common primary tumor in patients developing brain metastasis. This study was performed to develop and validate a survival score particularly for this group of patients. PATIENTS AND

methodsIn this study, the data of 514 patients treated with whole-brain radiotherapy (WBRT) alone for brain metastasis from NSCLC were retrospectively analyzed. The patients were divided into a test group (n = 257) and a validation group (n = 257). In the multivariate analysis of the test group, gender, performance status, and extracranial metastases were independent predictors of survival and, therefore, included in the scoring system. The score for each of the three factors was obtained from the 6-month survival rate (in %) divided by 10. The total scores that represented the sum of the three scores were 5, 8, 9, 11, 12, or 15 points. Three prognostic groups were formed according to the total scores.

resultsThe 6-month survival rates in the test group were 9 % for 5-9 points (group A), 54 % for 11-12 points (group B), and 79 % for 15 points (group C). In the validation group the 6-month survival rates were 14, 56, and 78 %, respectively. The comparisons between the prognostic groups A, B, and C of the test and the validation group did not reveal any significant differences.

conclusionThis new score appears valid and reproducible. It can help predict the survival of patients with brain metastasis from NSCLC.
