Rates and Predictors of 30-Day Readmissions in Patients Undergoing Bariatric Surgery in the US: a Nationwide Study.
Article in Obesity surgery, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
backgroundAmong various therapeutic options for morbid obesity, bariatric surgery (BS) is now considered one of the most effective methods of weight loss. We decided to perform an analysis to look at 30-day all-cause readmission and independent predictors of readmission in patients undergoing BS.
methodsWe queried the 2017 Nationwide Readmission Database (NRD) using ICD-10-CM diagnosis codes to identify all adult patients who underwent BS from January 1 to November 30, 2017. Outcomes assessed were 30-day readmission rates, mortality, length of stay (LOS) and hospitalization costs, and independent predictors of readmission.
resultsA total of 182,848 adult patients underwent BS during hospitalization in 2017, with in-hospital mortality rate of 0.52% (951). Of the patients discharged, 4.99% (9088) patients were readmitted within 30 days. The most common primary diagnosis at readmission was "Other complications of other bariatric surgery". When compared with index admission, readmitted patients had higher in-hospital mortality (0.52% vs 2.06%, p < 0.01), increased mean LOS (2.94 days vs 5.94 days, p < 0.01) but lower mean hospitalization charges ($67,763 vs $66,065, p < 0.01). Increasing age (HR 1.01, 95% CI: 1.006-1.014, p < 0.01), longer LOS (HR 1.01, 95% CI: 1.008-1.014, p < 0.01), higher comorbidity score (HR 1.15, 95% CI: 1.12-1.18, p < 0.01), CHF (HR 1.19, 95% CI: 1.01-1.42, p < 0.05), and AKI (HR 1.64, 95% CI: 1.34-2.02, p < 0.01) were independently associated with increased likelihood of 30-day readmission.
conclusionThis study shows that almost 5% patients undergoing bariatric surgery are readmitted within 30 days of discharge in the US. Further studies are needed to assess the high-risk populations to understand the reasons predisposing to early readmission.
