PRE- AND POSTOPERATIVE IN BARIATRIC SURGERY: SOME BIOCHEMICAL CHANGES.
Article in Arquivos brasileiros de cirurgia digestiva : ABCD = Brazilian archives of digestive surgery, 2016. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT03489538 (Homocysteine After Laparoscopic Roux-enY Gastric Bypass), which is not on this map. Cited by 2 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.

Abstract
Background: The bariatric surgery may cause some nutritional deficiencies. Aim: To compare the serum levels of biochemical markers, in iimmediate post-surgical patients who were submitted to bariatric surgery. Methods: Non-concurrent prospective cross-sectional study. The analysis investigated data in medical charts of pre-surgical and immediate post-surgical patients who were submitted to bariatric surgery, focusing total cholesterol, HDL cholesterol, LDL cholesterol, triglycerides, C reactive protein, vitamin B12 levels, folic acid, homocysteine values, iron and serum calcium at the referred period. Results: Twenty-nine patients of both genders were evaluated. It was observed weight loss from 108.53 kg to 78.69 kg after the procedure. The variable LDL-c had a significant difference, decreasing approximately 30.3 mg/dl after the surgery. The vitamin B12 serum average levels went from 341.9 pg/ml to 667.2 pg/ml. The triglycerides values were in a range of 129.6 mg/dl-173.3 mg/dl, and 81.9 mg/dl-105.3 mg/dl at the pre- and postoperative respectively. CRP levels fall demonstrated reduction of inflammatory activity. The variable homocysteine was tested in a paired manner and it did not show a significant changing before or after, although it showed a strong correlation with LDL cholesterol. Conclusion: Eligible patients to bariatric surgery frequently present pre-nutritional deficiencies, having increased post-surgical risks when they don´t follow an appropriate nutritional follow-up.
