1 · What the graph read from 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.

2 · The registry

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

backgroundThere is an increased prevalence of subclinical hypothyroidism (SCH) in patients with obesity. It is unclear if this biochemical abnormality may be a secondary phenomenon of obesity or a real hypothyroid state.

methodsA retrospective study of all the morbidly obese patients undergoing laparoscopic sleeve gastrectomy as bariatric procedure between October 2007 and November 2012 was performed. Weight loss, body mass index (BMI) and excess weight loss, baseline glucose, lipid profiles, and TSH levels were obtained before operation and postoperative determinations at 3, 6, and 12 months after surgery.

resultsSixty patients were included. Prevalence of subclinical hypothyroidism was 16.7% preoperatively, 10% at 3 months, 3.3% at 6 months, and 1.7% at 12 months. A significant correlation could be established between TSH decrease and weight loss at 12 months (Pearson 0.603; p = 0.007). TSH decrease showed a significant correlation with glucose and glycated hemoglobin decrease from 6th month onwards. Referring to lipid profile, an association of TSH decrease with total cholesterol, LDL cholesterol, or HDL cholesterol could not be determined. A significant association between TSH decrease and triglycerides and cardiovascular risk index triglycerides/HDL cholesterol reductions could also be established 12 months after surgery.

conclusionsSCH is usually corrected after bariatric surgery, while there are no significant changes in total or LDL cholesterol. This suggests that, in morbidly obese subjects, SCH is, in most patients, just a consequence of the abnormal fat accumulation and not a real hypothyroid state.
