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

purposeSurgery for children in developing nations is challenging. Endoscopic third ventriculostomy (ETV) is an important surgical treatment for childhood hydrocephalus and has been performed in developing nations, but with lower success rates than in developed nations. It is not known if the lower success rate is due to inherent differences in prognostic factors.

methodsWe analyzed a large cohort of children (≤20 years old) treated with ETV in developed nations (618 patients from Canada, Israel, United Kingdom) and developing nations of sub-Saharan Africa (979 patients treated in Uganda). Risk-adjusted survival analysis was performed.

resultsThe risk of an intra-operative ETV failure (an aborted procedure) was significantly higher in Uganda regardless of risk adjustment (hazard ratio (HR), 95% confidence interval (CI), 11.00 (6.01 to 19.84) P<0.001). After adjustment for patient prognostic factors and technical variation in the procedure (the use of choroid plexus cauterization), there was no difference in the risk of failure for completed ETVs (HR, 95% CI, 1.04 (0.83 to 1.29), P=0.74).

conclusionsThree factors account for all significant differences in ETV failure between Uganda and developed nations: patient prognostic factors, technical variation in the procedure, and intra-operatively aborted cases. Once adjusted for these, the response to completed ETVs of children in Uganda is no different than that of children in developed nations.
