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

backgroundLong-term studies evaluating self-expandable metal stents in patients who have unresectable malignant hilar biliary obstruction (UMHBO) after surgical reconstruction of the intestine remain inadequate. We developed a side-by-side (SBS) technique using a two-channel endoscope to place self-expandable metal stents in patients with UMHBO occurring after Billroth II reconstruction.

aimsWe validated the long-term outcomes obtained with this technique.

methodsThe study group comprised seven patients with UMHBO in whom we attempted to place metal stents by the SBS technique using a two-channel scope. The procedure was validated retrospectively.

resultsThe technical success rate was 86% and functional success rate was 100%. The median time to recurrent biliary obstruction (RBO) was 222 days (95% CI 4.9-439.1). Besides RBO, there were no other complications.

conclusionsThe SBS procedure performed using a two-channel scope is a safe and useful new technique for the treatment of UMHBO occurring after Billroth II reconstruction.
