Nutrient Status 9 Years After Biliopancreatic Diversion with Duodenal Switch (BPD/DS): an Observational Study.
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 29 papers, 4 of them syntheses that pooled 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.
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
backgroundSince biliopancreatic diversion with duodenal switch (BPD/DS) produces hypoabsorption, evaluation of long-term nutrient changes is appropriate.
methodsMeasurements of micronutrients, trace elements, PTH, iron studies, and protein were completed for consented patients at baseline prior to surgery and at yearly intervals. The patients were advised and supplements were adjusted by blood studies with compliance checks. Independent t tests and ANOVAs compared changes between cross-sectional cohorts based on follow-up time from surgery. A p value of 0.05 was considered significant.
resultsBetween 1999 and 2010, 284 patients had BPD/DS. At baseline, nutrient analysis was available for only 190 patients (70% women), age 42.7 ± 10.0 years, BMI 53.0 ± 11.9 kg/m
conclusionsMajor deficits in nutrient status occurred and persisted after surgery although supplementation was prescribed. Interventions are mandated to avoid nutrient deficiency.
