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

backgroundThe Roux-en-Y gastric bypass (RYGB) still remains the gold standard in bariatric surgery. However, no consensus exists on the optimal limb lengths to induce maximum weight reduction. The aim of the present study was to assess the effect of a longer alimentary limb (AL) length on weight reduction after RYGB.

methodsA retrospective analysis of a prospectively collected database of patients who underwent a primary laparoscopic RYGB between January 2001 and March 2011 was performed. Patients received a short AL (SAL; 100 cm) or a long AL (LAL; 150 cm). Primary outcome was weight loss, and secondary outcomes were short- and long-term complication rates.

resultsA total of 768 patients received a RYGB during the study period. Of these, 730 consecutive patients were included for long-term analysis and had a mean follow-up (FU) of 37 ± 26 [range 0-120] months; 360 (47 %) patients received a SAL RYGB. Overall %TBWL was 33 ± 9 % after 2 years (FU 74 %) and 28 ± 12 % after 5 years (FU 20 %). No significant differences in %TBWL were found between SAL RYGB and LAL RYGB during the study period. The 30-day mortality rate was 0.13, 9 % overall short-term complication rate and 19 % cumulative long-term complication rate. No differences in complications were found between SAL and LAL RYGB patients.

conclusionLengthening of the alimentary limb from 100 to 150 cm did not affect post-RYGB weight loss. Overall complication rates were low and comparable in this series of RYGB patients.
