Bariatric Surgery Following Total Shoulder Arthroplasty Increases the Risk for Mechanical Complications Including Instability and Prosthetic Loosening.
Article in HSS journal : the musculoskeletal journal of Hospital for Special Surgery, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
backgroundWhile extensive literature has been published on the risks and benefits of bariatric surgery (BS) prior to and following lower-extremity arthroplasty, no similar investigations have been performed on the impact of BS prior to total shoulder arthroplasty (TSA). PURPOSE: The objective of the present study was to compare the incidence of mechanical complications in morbidly obese patients who undergo TSA: those who undergo BS following TSA compared with those who do not undergo BS, and those who undergo BS after TSA compared with those who undergo BS prior to TSA.
methodsA Medicare database was queried for morbidly obese patients who underwent BS either before or after TSA, as well as those who underwent TSA but no BS. Of 12,277 morbidly obese patients who underwent TSA between 2005 and 2014, 304 underwent BS (165 of them prior to TSA and 139 following TSA) and 11,923 did not undergo BS. Rates of mechanical complications were then compared between groups using a logistic regression analysis.
resultsPatients who underwent BS after TSA had significantly higher rates of mechanical complications (12.9%) compared to controls (8.8%) or patients who underwent prior BS (7.9%). Patients who underwent BS after TSA had higher rates of both instability (7.9%) and loosening (8.6%) than did controls (5.1 and 4.9%, respectively) or patients who underwent BS before TSA (4.8 and 4.2%, respectively).
conclusionsBS following TSA is associated with increased rates of mechanical complications, including instability and loosening, compared to BS prior to TSA. These findings suggest that it may be prudent to consider performing BS prior to TSA in morbidly obese patients, rather than waiting until after TSA is performed.
