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

backgroundThis multicenter study aimed to create and validate a scoring system for survival of patients with metastatic spinal cord compression (MSCC) from non-small cell lung cancer (NSCLC).

methodsThe entire cohort of 356 patients was divided in a test group (N = 178) and a validation group (N = 178). In the test group, nine pre-treatment factors including age, gender, Eastern Cooperative Oncology Group performance status (ECOG-PS), number of involved vertebrae, pre-radiotherapy ambulatory status, other bone metastases, visceral metastases, interval from cancer diagnosis to radiotherapy of MSCC, and the time developing motor were retrospectively analyzed.

resultsOn multivariate analysis, survival was significantly associated with ECOG-PS, pre-radiotherapy ambulatory status, visceral metastases, and the time developing motor deficits. These factors were included in the scoring system; the score for each factor was determined by dividing the 6-month survival rate (in %) by 10. The risk score represented the sum of the scores for each factor. According to the risk scores, which ranged from 6 to 19 points, three prognostic groups were designed. The 6-month survival rates were 6% for 6-10 points, 29% for 11-15 points, and 78% for 16-19 points (p < 0.001). In the validation group, the 6-month survival rates were 4%, 24%, and 76%, respectively (p < 0.001).

conclusionsSince the survival rates of the validation group were similar to those of the test group, this score can be considered reproducible. The scoring system can help when selecting the individual treatment for patients with MSCC from NSCLC. A prospective confirmatory study is warranted.
