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

purposeThe aims of this study were to (1) characterize the prevalence of hypoalbuminemia (HA), (2) compare complication rates among HA and non-HA patients, and (3) determine the influence of HA on postoperative complications and 30-day mortality among bariatric surgery patients. MATERIALS AND

methodsData was extracted from the MBSAQIP registry from 2015 to 2018. A presurgical serum albumin level of [Formula: see text] 3.5 g/dL was used to organize the patient population into HA and non-HA cohorts. Bivariate analysis and multivariable logistic regression modeling were used.

resultsOf 590,971 patients, 42,618 (7.2%) were identified as having serum albumin levels [Formula: see text] 3.5 g/dL. HA patients were younger (44.0 + / - 11.9 vs. 44.5 + / - 12.0 years; p < 0.0001), were of increased BMI (48.5 + / - 9.0 kg/m

conclusionWe identified HA as one of the greatest modifiable factors predictive of serious complications. Adoption of strategies to identify and improve preoperative serum albumin levels may reduce overall serious complications among elective bariatric surgery patients.
