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

backgroundThe aim of this study was to establish a correlation of tumor topography and peritumoral brain edema with the therapeutic response to intranasal administration of perillyl alcohol (POH) in a cohort of patients with recurrent malignant gliomas.

methodsThe retrospective study reviewed clinical and neuroradiological data from patients with recurrent malignant gliomas who received intranasal daily administration of POH 440 mg. The following parameters were assessed: demographic characteristics, initial symptoms, overall survival, tumor topography and tumor size, presence of midline shift and extent of peritumoral edema. Statistical analysis was carried out with log rank tests and overall survival as assessed by Kaplan-Meier method including 95% confidence intervals.

resultsA cohort of 67 patients included 52 (78%) with glioblastoma (GBM), ten (15%) with anaplastic astrocytoma (AA) and five (7%) with anaplastic oligodendroglioma (AO). Accordingly to tumor topography lobar localization was present in all (5/5) AO; eight (8/10) and 41 GBM patients whereas in the basal ganglia two AA and 11 GBM patients. It was also observed a relation between the tumor size and area of peritumoral brain edema (PTBE). Patients with good therapeutic response showed reduction of tumor size and PTBE area, but poor prognosis was associated with lack of response to treatment and persistence of high PTBE. Patients with tumor in the basal ganglia survived significantly longer than those with lobar gliomas (log rank test, p = 0.0003). Presence of midline shift (>1 cm) was a statistically significant risk factor for shorter survival (log rank test, p = 0.0062)

conclusionsThis study suggests that: (1) patients with recurrent gliomas with localization in the basal ganglia survive significantly longer than those with tumors at lobar localization; (2) presence of PTBE contributes to symptoms, likely to be implicated in the morbidity and invading potential of malignant gliomas. These findings support the theory that interaction between glioma cells at distinct brain microenvironment can influence the oncobiological behavior of glioma cells and ultimately to the prognosis.
