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

OBJECTIVE(S): Monitoring and prevention of long-term nutrient deficiency after laparoscopic Roux-en-Y gastric bypass (LRYGB) remains ill defined due to limited surgical follow-up after bariatric surgery. This study compared nutrient supplementation as well as surgeon and primary care physician (PCP) follow-up between patients with short-term versus long-term follow-up.

methodsAll patients undergoing LRYGB at a single institution in 2004 (long-term group, n = 281) and 2012-2013 (short-term group, n = 149) were evaluated. Prospectively collected database, electronic medical record (EMR) review and telephone survey were used to obtained follow-up for both cohorts. Multivariate logistic regression was used to assess factors independently predicting multivitamin use.

resultsComplete follow-up was achieved in 172 (61 %) long-term and 107 (72 %) short-term patients. We demonstrate a significant difference (p < 0.0001) in time since last surgeon follow-up (13.3 ± 7.8 vs 86.9 ± 39.9 months) for the long-term group with no difference in PCP follow-up, (3.1 ± 4.3 vs 3.7 ± 3.4). Nutrient supplementation was higher in the short-term group, including multivitamin (70.3 vs 58.9 %, p < 0.05), iron (84.2 vs 67.1 %, p = 0.02), and calcium (49.5 vs 32.9 %, p = 0.01). After adjusting for interval since surgery, %EBMI and current comorbidities logistic regression (c = 0.797) demonstrated shorter time since last surgeon visit was independently predictive of multivitamin use (p = 0.001).

conclusionsWhile it appears patients prefer to follow-up with their PCP, this study reveals a large disparity in malnutrition screening and nutrient supplementation following LRYGB. Therefore, implementation of multidisciplinary, best-practice guidelines to recognize and prevent malnutrition is paramount in the management of this growing population of high-risk patients.
