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

introductionLong-term data indicate that patients who underwent metabolic bariatric surgery have a higher risk of developing nutritional complications. Therefore, it is of utmost importance to monitor their nutritional status.

methodsA scoping literature search was conducted in MEDLINE, EMBASE, CINAHL, and TRIP database to identify clinical practice guidelines for nutritional screening before and after metabolic bariatric surgery from learned societies. For full coverage, all websites of learned societies affiliated with the World Obesity Federation were searched. Clinical practice guidelines were eligible if they contained recommendations for nutritional screening before and after sleeve gastrectomy or Roux-en-Y gastric bypass. Content was screened by two reviewers for timing, biochemical markers and cut-off values, and biochemical assays for nutritional screening.

resultsNine eligible clinical practice guidelines co-authored by 26 learned societies were identified. All guidelines provided recommendations for both bariatric procedures except for one. Majority of guidelines endorsed nutritional screening before surgery and at 3, 6, 12, and 24 months after surgery, and annually thereafter. Pre- and postoperative screening recommendations were available for iron, vitamin B DISCUSSION: The clinical practice guidelines exhibited a high level of consistency for timing of screening, but not for the applied biochemical markers. Going forward, the primary focus should be on harmonizing recommendations for biochemical markers, and cut-off values.
