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

backgroundInconsistent results were reported by several studies that evaluated the effect of weight loss induced by bariatric surgery on thyroid function panel. This study is aimed at evaluating this effect on thyroid-stimulating hormone (TSH) and thyroid hormone replacement dosages in obese population with overt and subclinical hypothyroidism (SH).

methodsA retrospective study was performed on all morbidly obese patients with previous diagnosis of overt and subclinical hypothyroidism who underwent laparoscopic sleeve gastrectomy from October 2009 to January 2017. The correlation between TSH and body mass index (BMI) and the effect of weight loss induced by bariatric surgery on TSH were investigated.

resultsThe prevalence of overt and SH in morbidly obese patients was 10.8% and 7.2%, respectively. Thirty-six hypothyroid patients and 67 subclinically hypothyroid patients were included in the study. Hypothyroidism improved in 44.5% of patients and completely resolved in 22.2%, and 33.3% experienced no change. Ninety-one percent of SH patients completely resolved, 6% improved, but 3% worsened, with one patient developed hypothyroidism. Both groups achieved a significant decrease in postoperative BMI. A positively statistically significant association was found between BMI and TSH (p < 0.005).

conclusionsOur results favor the effect of laparoscopic sleeve gastrectomy in the obese population with overt and SH as shown by the majority of SH resolution and overt hypothyroidism improvement.
