Systematic review of obesity surgery mortality risk score--preoperative risk stratification in bariatric surgery.
Synthesis in Obesity surgery, 2012. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 28 papers, 1 of them a synthesis that pooled 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.
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
Bariatric surgery is the best long term treatment for morbid obesity. However, it carries risks of considerable morbidity and potential mortality. There is no published review on pre-operative identification of high-risk patients in bariatric surgery. This systematic review analyses obesity surgery mortality risk score (OS-MRS) as a tool for pre-operative prediction of mortality risk in bariatric surgery. Medline and Embase was systematically searched using the medical subjects headings (MeSH) terms 'bariatric surgery' and 'mortality' with further free text search and cross references. Studies that described OS-MRS to predict mortality risk after bariatric surgery were included in this review. Six studies evaluated 9,382 patients to assess the validity of OS-MRS to predict the mortality risk after bariatric surgery. Patient's age ranged from 19 to 67 years, and the body mass index ranged from 30 to 84. There were 83 deaths among the 9,382 patients (0.88 %) with individual studies reporting a mortality range from 0 % to 1.49 %. There were 13 deaths among 4,912 (0.26 %) class A patients, 55 deaths among 4,124 (1.33 %) class B patients and 15 deaths among 346 (4.34 %) class C patients. Mortality in classes A, B and C was significantly different from each of the other two classes (P < 0.05, χ(2)). This systematic review confirms that OS-MRS stratifies the mortality risk in the three-risk classification subgroups of patients. The OS-MRS can be used for pre-operative identification of high-risk patients undergoing primary Roux-en-Y gastric bypass surgery.
