Consequences of Small Intestinal Bacterial Overgrowth in Obese Patients Before and After Bariatric Surgery.
Trial report in Obesity surgery, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 41 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
BACKGROUND AND
aimsSmall intestinal bacterial overgrowth (SIBO) has been described in obese patients. The aim of this study was to prospectively evaluate the prevalence and consequences of SIBO in obese patients before and after bariatric surgery. PATIENTS AND
methodsFrom October 2001 to July 2009, in obese patients referred for bariatric surgery (BMI >40 kg/m
resultsThree hundred seventy-eight (mean ± SD) patients who performed a BT before and/or after surgery were included: before surgery, BT was positive in 15.4 % (55/357). After surgery, BT was positive in 10 % (2/20) of AGB and 40 % (26/65) of RYGBP (p < 0.001 compared to preoperative situation). After RYGBP, patients with positive BT had similar vitamin levels, a lower caloric intake (983 ± 337 vs. 1271 ± 404 kcal/day, p = 0.014) but a significant lower weight loss (29.7 ± 5.6 vs. 37.7 ± 12.9 kg, p = 0.002) and lower percent of total weight loss (25.6 ± 6.0 vs. 29.2 ± 6.9 %, p = 0.044).
conclusionIn this study, SIBO is present in 15 % of obese patients before bariatric surgery. This prevalence does not increase after AGB while it rises up to 40 % of patients after RYGBP and it is associated with lower weight loss.
