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

Management of pediatric intracranial ependymomas poses a major challenge, and optimal treatment remains controversial. We sought to investigate the roles of surgery, radiation, and chemotherapy in a historical cohort. Thirty-nine children, age 21 or younger, with non-metastatic intracranial ependymomas were treated from 1972 to 2008. Median age was 8 years (range 0.2-19.1). Twenty-one patients (54%) underwent GTRs, and 18 (45%) underwent STRs. Twenty-six patients (67%) received upfront adjuvant RT (67%), and 14 (44%) received adjuvant chemotherapy. Twenty-four patients had disease recurrence and 12 died. Only one patient recurred after 5 years. Median PFS was 2.7 years and median OS was 20 years. Fifteen year PFS and OS were 30 and 67%. Adjuvant RT was associated with improved PFS (P = 0.045), and remained significant after adjusting for EOR (P = 0.04). Greater EOR trended towards prolonged survival, but did not reach statistical significance (P = 0.156). Of the patients that underwent GTR, the median PFS was 38 months for those treated with adjuvant RT versus 30 months for those that were not treated with RT. Of the patients that had STR, the median PFS for those treated with RT was 26.3 months versus 6.9 months for those were not treated with RT. In conclusion, for localized intracranial pediatric ependymomas, adjuvant RT is associated with improved PFS, even after adjusting for EOR. Our findings suggest the benefit of RT even in the presence of GTR. Future prospective studies with larger sample number are needed to validate our findings.
