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 present study aims to assess the therapeutic effect of whole brain radiotherapy (WBRT) for brain metastases from non-small cell lung cancer stratified by graded prognostic assessment (GPA) through meta-analysis.

methodsThe Cochrane Library, PubMed, Ovid (Elsevier) were retrieved. The included randomized controlled trials (RCT) were evaluated, and the statistical analysis was performed using RevMan 5.3 software. Cochrane handbook was applied to evaluate the methodological quality. Statistical significance was considered as P < .05.

resultsThere were 2 randomized control trials identified eligible for the meta-analysis. Stereotactic radiosurgery (SRS)+WBRT did not significantly improved overall survival (OS) in 2 subgroups. (GPA <2: HR, 0.93; 95% confidence interval [CI], 0.61-1.40; P = .71), (GPA ≥2: HR, 1.28; 95% CI, 0.58-2.80; P = .54). The use of SRS+WBRT significantly extended brain tumor recurrence (BTR) free time in both subgroups (GPA <2: HR, 5.46; 95% CI: 2.09-14.22; P = .0005), (GPA ≥2: HR, 4.24; 95% CI: 2.24-8.04; P < .00001). The meta-analysis showed salvage therapy was more frequent among the SRS-alone in 2 subgroups (GPA <2: RR, 5.83; 95% CI: 1.47-23.06; P = .01), (GPA ≥2: RR, 2.53; 95% CI: 1.30-4.93; P = .006). The rate of grade 3 or 4 late radiation toxic effects was similar in 2 subgroups between SRS and SRS+WBRT

conclusions: Because there are few studies to meet inclusion criteria, we cannot include more researches. The results of this analysis must be carefully interpreted in view of the unclear risk of bias in inclusion in the study. This meta-analysis of 2 randomized trails indicated that the combined treatment group did not show a survival benefit over SRS alone. However, SRS+WBRT improved BTR free time in the subgroup both GPA <2 and GPA ≥2 with the similar grade 3 or 4 late radiation toxicities.
