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

Primary intracranial leiomyosarcomas (PILMSs) are extremely rare neoplasms, and their management remains unclear. The authors aimed to enunciate the radiological features and design a treatment protocol based on previously published cases combined with our series. Clinical data from all 12 cases of PILMS treated at their institute between 2008 and 2018 were reviewed. Meanwhile, they searched the Ovid MEDLINE, Embase, PubMed, Web of Science and Cochrane databases using the keywords "leiomyosarcoma" and "intracranial," "central nervous system," "cerebral," or "brain" Previously published data were processed and used according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. The authors' cohort included 4 males (33.3%) and 8 females (66.7%) ranging in age from 13 to 67 years with a mean of 44.1 ± 5.0 years. Gross total resection (GTR), subtotal resection, and partial resection were achieved in 8 (66.7%), 3 (25%), and 1 (8.3%) patient, respectively, and only four patients (33.3%) received adjuvant therapy after surgery. After a mean follow-up of 30.5 ± 7.6 months, 6 patients (50%) experienced recurrences, and all of them died at the final. Twenty-seven patients (15 were male and 12 were female), in the literature cases, were identified between January 1980 and November 2019, presenting with PILMS. GTR and non-GTR were achieved in 21 (77.8%) and 6 (22.2%) patients, respectively. Postoperative radiotherapy was administrated in 17 patients (63.0%), and postoperative chemotherapy was administrated in 9 patients (33.3%), After a mean follow-up of 22.2 ± 4.1 months, recurrence and death occurred in 8 (36.4%) and 4 (14.8%) cases, respectively. In the pooled cases, the univariate analysis model revealed that only GTR was a significantly favorable factor for increased progression-free survival (hazard ratio 0.270, 95% confidence interval = 0.093-0.787, p = 0.016) and overall survival (hazard ratio 0.255, 95% confidence interval = 0.073-0.890, p = 0.032). GTR was recommended as an optimal treatment; meanwhile, postoperative radiation was also a choice to help increase the survival of patients of PILMS.
