The impact of postoperative radiation therapy on patterns of failure and survival improvement in patients with intracranial hemangiopericytoma.

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.
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
Because of the rarity of intracranial hemangiopericytomas (HPCs), the role of postoperative radiation therapy (PORT) in the management of HPC remains unclear. This study therefore analyzed the effects of PORT on patterns of failure and survival improvement in patients with HPC. Fifty-two patients surgically treated for intracranial HPC at our institution between 1992 and 2013 were retrospectively analyzed. Patterns of failure were subdivided into local recurrence, regional metastasis, and distant metastasis. Multivariate Cox proportional hazards models were used to assess factors prognostic of treatment failure and survival, and a time-dependent Cox proportional hazards models were used to investigate the correlations between patterns of failure and death. Of the 52 patients, 45 (87 %) underwent gross total resection, and 39 (75 %) received PORT. PORT significantly lengthened local control (LC) and overall survival (OS), by 14 and 13 months, respectively, independent of the extent of resection. Patients who did and did not receive PORT had 5 year LC rates of 97 and 44 %, respectively (HR .05, P = .002); and 10 year OS rates of 83 and 25 %, respectively (hazard ratio (HR) .20, P = .008). PORT, however, did not show preventive effects on regional and distant metastases. The main patterns of failure were local recurrence in patients who did not receive PORT and distant metastasis in those who received PORT. Regional metastasis was a main immediate cause of death (P < .001), and tended to occur more frequently and earlier in patients not receiving PORT.
