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

backgroundSurgical resection is necessary to conduct a pathological biopsy and to achieve a reduction of intracranial pressure in low-grade gliomas patients. This study aimed to determine whether a greater extent of resection would increase the overall 5-year and 10-year survival of patients with low-grade gliomas.

methodsThe studies addressing relationship between the extent of resection and the prognosis of low-grade gliomas updated until March 2017 were systematically searched in two databases (Pubmed and EMBASE). The relationships among categorical variables were analyzed using an odds ratio (OR) and a95% confidence interval (CI). Significance was established using CIs at a level of 95% or P < 0.05. Funnel plot was used to detect the publication bias.

resultsTwenty articles (a total of 2128 patients) were identified. The meta-analysis showed that the 5-year (Odds ratio (OR), 3.90;95% Confidence Interval (CI), 2.79~5.45; P < 0.01; Z = 7.95) and 10-year OS (OR, 7.91; 95%CI, 5.12~12.22; P < 0.01; Z = 9.33) associated with gross total resection (GTR) were higher than those associated with subtotal resection (STR). Similarly, as compared with biopsy(BX), the 5-year and 10-year OS were higher after either GTR (5-year: OR, 5.43; 95%CI, 3.57~8.26; P < 0.01; Z = Z = 7.9; 10-year: OR, 10.17; 95%CI, 4.02~25.71; P < 0.00001; Z = 4.9) or STR (5-year: OR, 2.59; 95%CI, 1.81~ - 3.71; P < 0.00001; Z = 5.19; 10-year: OR, 2.21; 95%CI, 1.164.25; P = 0.02; Z = 2.39).

conclusionsOur research found that a greater extent of resection could significantly increase the OS of patients with low-grade gliomas.
