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

Pseudoprogression (psPD) is a radiation-induced toxicity that has substantial neurological consequence in glioblastoma (GBM) patients. MGMT promoter methylation has been shown to be an important prognostic factor of psPD, but the significance of extent of resection (EOR) remains unclear. We performed a retrospective analysis on newly diagnosed GBM patients with assessable MGMT promoter status who underwent the Stupp protocol. EOR was grouped into gross total resection (GTR), subtotal resection (STR), partial resection (PR) and stereotactic biopsy. Contrast enhancing lesion enlargement was classified as psPD or non-psPD. Among a total of 101 patients, GTR, STR, PR and stereotactic biopsy was performed in 57 (56.4%), 34 (33.7%), 9 (8.9%) and 1 patient (1%), respectively. Follow-up imaging at the end of Stupp protocol classified 45 patients (44.6%) as psPD and 56 (55.4%) as non-psPD. psPD was observed in 24 (61.5%) of 39 patients with methylated MGMT promoter and 21 (33.9%) of 62 patients with unmethylated MGMT promoter (p < 0.01). psPD was documented in 17 (29.8%), 19 (55.9%), 8 (88.9%) and 1 (100%) patient with GTR, STR, PR and stereotactic biopsy (p < 0.01), respectively. On multivariate analysis MGMT promoter status (OR 3.36, 95% CI 1.36-8.34) and EOR (OR 4.12, 95% CI 1.71-9.91) were independent predictors of psPD. A Cox proportional hazards model showed that MGMT status (HR 2.51, p < 0.01) and EOR (HR 2.99, p < 0.01) significantly influenced survival. MGMT status and EOR have a significant impact on psPD. GTR can reduce the side effects of psPD and prolong survival.
