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

purposeForamen magnum decompression is a common surgical treatment for Chiari type 1 malformation (CM-1). There are several methods for the intervention to the dura matter such as dural plasty sectioning the dura, also removing the outer membrane of the dura without intradural manipulation. We compared retrospectively our cases with a presentation of illustrative cases. Finally, we add our comments to the worldwide questionnaire which was offered.

methodsTwenty-six patients (9 males and 17 females) who underwent surgery from 2010 to 2019 were included. The age distribution was 1 to 55 years old (mean: 16.4 ± 11.3).They were divided into two groups, group A which underwent outer membranectomy and group B which underwent dural plasty.

resultsThere were 15 cases in group A and 11 cases in group B, and tonsillectomy was performed in 5 cases out of the 11. Symptoms improved in 7 cases (47%) and 5 cases (45%), respectively. Improvement of the syrinx was seen in 14 cases (93%) and 10 cases (90.9%), respectively. No complications were seen in group A; however, one CSF leak and 2 pseudomeningoceles were seen in group B.

conclusionThe number of our cohort is not large enough to analyze statistics, but it seems that outer membranectomy is similar to dural plasty in terms of the results of surgery with a lower risk of complications for the treatment in non-complicated CM-1.
