Observational study in Obesity surgery, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 12 papers, 1 of them a synthesis that pooled it.

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

backgroundMany studies have shown that hyperfiltration induced by obesity decreases after bariatric surgery, while others also showed an increase in glomerular filtration rate (GFR). Furthermore, the factors that influence GFR after bariatric surgery have been poorly studied. The objective was to study the impact of bariatric surgery on renal function and clarify the factors that determine the evolution of GFR after surgery.

methodsWe prospectively evaluated GFR (assessed with 24-h urinary clearance of creatinine) in all patients who underwent bariatric surgery between 2004 and 2014, before and 1 year after surgery. The links between GFR changes and usual clinical and biological parameters were studied.

resultsThree hundred twenty-three patients with complete urine datasets were included (age 43 ± 11 year, M/F 49/274, BMI 46 ± 7 kg/m

conclusionGFR decreased after bariatric surgery in subjects with hyperfiltration, but increased in subjects with renal failure. Changes in body mass, protein intake, and blood pressure appeared to be the main determinants of GFR evolution after surgery.
