The effect of hospital teaching status on outcomes in bariatric surgery.
Article in Surgery for obesity and related diseases : official journal of the American Society for Bariatric Surgery, 2017. 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
backgroundStudies have shown conflicting effects of resident involvement on outcomes after laparoscopic bariatric surgery. Resident involvement may be a proxy for a teaching environment in which multiple factors affect patient outcomes. However, no study has examined outcomes of laparoscopic bariatric surgery based on hospital teaching status.
objectiveTo compare outcomes after laparoscopic Roux-en-Y gastric bypass (LRYGB) and laparoscopic sleeve gastrectomy (LSG) between teaching hospitals (THs) and nonteaching hospitals (NTHs).
settingRetrospective review of a national database in the United States.
methodsThe Nationwide Inpatient Sample database (2011-2013) was reviewed for obese patients who underwent LRYGB or LSG. Patient demographic characteristics and outcomes were analyzed according to hospital teaching status. Primary outcome measures included risk-adjusted inpatient mortality and serious morbidity.
resultsWe analyzed 32,449 LRYGBs and 26,075 LSGs. There were 35,160 (60.1%) cases performed at THs and 23,364 (39.9%) cases performed at NTHs. At THs, the distribution of LRYGB versus LSG cases was 20,461 (58.2%) versus 14,699 (41.8%), respectively; at NTHs, the distribution was 11,988 (51.3%) versus 11,376 (48.7%), respectively. For LRYGB, there were no significant differences between THs versus NTHs in mortality (AOR 1.14; P = 0.99), but there was an increase in odds of serious morbidity at THs (AOR 1.36; P<0.001). For LSG, there were no significant differences between THs versus NTHs for mortality (AOR 1.15; P = 0.99) or serious morbidity (AOR 1.03; P = 0.99).
conclusionsThere is an association between THs and increased serious morbidity for LRYGB, but hospital teaching status has no effect on morbidity or mortality after LSG. Further research is warranted to elucidate the reasons for these associations.
