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

backgroundEndoscopic third ventriculostomy success score (ETVss) is widely utilised to predict outcomes for ETV. Accurate prediction of success for a procedure is of vital importance both for selecting the optimal management plan and for obtaining informed consent. Existing literature demonstrates a variety of opinions on the accuracy of the currently utilised ETVss and recommends a range of techniques to reduce the number of subsequent ventriculo-peritoneal (VP)-shunt insertions, prompting the present study.

methodsWe retrospectively analysed data for ETV cases since 2007 to review success rate in our regional paediatric neurosurgical centre and if the currently utilised ETVss successfully predicted outcomes. Failed ETV cases were defined as any patient who received a VP-shunt at any time following ETV. Data was analysed with MS Excel

results44 ETVs were performed over 13 years with approximately equal distribution between male and female patients; median age 7 years (IQR 4-13 years). Overall, mean ETVss for these 44 procedures was 78%; actual success rate was 70% with no statistically significant difference between them (p = 0.286; Welch two sample t-test). Accuracy of ETVss varied with pathology: tectal gliomas (mean ETVss 75% and actual success 78%); cerebellar tumours (mean ETVss 85% and actual success 81%); other tumours (mean ETVss 75% and actual success 81%); aqueduct stenosis (mean ETVss 71% and actual success 69%); and other pathologies (mean ETVss 70% and actual success 60%). < 1 month and 1-6 months and 1-10 years and > 10 years contributed equally to the accuracy of ETVss.

conclusionNon-telencephalon tumours and obstruction at the level of the mid-brain are most strongly associated with successful ETV outcome. These findings can be used to modify the currently utilised ETVss to further improve accuracy of outcome prediction. We recommend a modified-ETVss (m-ETVss) and a future larger adequately powered prospective study to validate this.
