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

backgroundAn underlying major aim of bariatric surgery is weight loss and its long-term maintenance. In spite of this, most studies regarding weight loss after surgical treatment of morbid obesity show 3-year follow-up results. We evaluated the effectiveness of silastic ring Roux-en-Y gastric bypass (SR-RYGBP) in promoting significant weight loss after an 8-year follow-up at the Londrina State University Hospital.

methodsFrom May 1999 to December 2000, 211 morbidly obese patients were submitted to SR-RYGBP by the same surgical team. The study's design was longitudinal, prospective, and descriptive. The analysis of postoperative weight decrease was based on excess weight loss in percentage (%EWL) and the calculation of body mass index. Therapeutic failure was considered when patients lost <50% of excess weight.

resultsPatients lost to follow-up were 36.5%; therefore, 134 patients were included in this study. The average global EWL was 67.6 ± 14.9% on the first postoperative year, 72.6 ± 14.9% on the second year, 69.7 ± 15.1% on the fifth postoperative year, and 66.8 ± 7.6% on the eight postoperative year. Surgical treatment failure occurred in 15 patients (7.1%) over 8 years.

conclusionsSR-RYGBP was effective in promoting and maintaining weight loss in the long term with a low failure rate.
