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

purposeThe aim of the study is to compare the outcomes of patients treated with secondary Roux-en-Y gastric bypass (RYGB) after adjustable gastric banding (AGB) or vertical banded gastroplasty (VBG) with those of patients having primary RYGB. MATERIALS AND

methodsPatients undergoing secondary RYGB after AGB or VBG between 1997 and 2004 with a minimal follow-up of 15 years were matched using a propensity score (according to gender, age, BMI, duration of follow-up) with comparable patients who underwent primary RYGB.

resultsThe mean follow-up was 16.50 years in the secondary RYGB group (N = 32) versus 16.33 years in the primary RYGB group (N = 32). Early postoperative complications rate was 6.25% in the secondary RYGBs versus 9.38% in the primary RYGBs (P = 1). Late postoperative complications and additional surgical procedures were 56.25% and 37.5% in the secondary and primary RYGB group, respectively (P = 0.21). Long-term (at 16-20 years) %TWL and %EWL were significantly lower (P < 0.01 and P = 0.013, respectively) after secondary RYGB (%TWL = 7.56%; %EWL = 17.15%) than after primary RYGB (%TWL = 24.51%; %EWL = 55.61%). Remission of obesity-related comorbidities was comparable (P > 0.05). Gastroesophageal reflux was more frequent after secondary RGYB-43.75% versus 25%, P < 0.05. Quality of life-Morehead-Ardelt II score (0.02 in secondary RYGB versus 0.69 in primary RYGB, P = 0.13), general self-assessment of health status and weight satisfaction were comparable.

conclusionSecondary RYGB after AGB or VBG is less efficient at weight loss, GERD remission and energy expenditure at 15 years after conversion. However, it is as effective for improvement/resolution of obesity-related comorbidities and is associated with similar QoL scores.
