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

backgroundStudies investigating the effects of bariatric surgery (BS) on the thyroid are quite limited. The aim of our study is to evaluate changes in thyroid function and thyroid morphology in patients after BS.

methodsThis retrospective study included a total of 122 patients. Of these, 33 underwent BS and 89 did not undergo surgery. In the BS group, preoperative and postoperative one-year thyroid function tests, changes in ultrasonographic findings, and contributing factors were evaluated, while in the control group, changes from baseline to one-year were examined.

resultsThere were no baseline differences between the groups in terms of demographic, laboratory and ultrasonographic data. In the BS group, TSH and fT3 levels significantly decreased (p = 0.005 and 0.002), with the decrease in TSH being independently associated with an increase in HDL-cholesterol (β = -0.018, p = 0.040). No significant changes in thyroid function were observed in the control group. Thyroid volume increased significantly in the control group but not in the BS group (p = 0.034 vs. 0.270). A significant increase in the largest nodule diameter was observed after BS (β = 2.656, p = 0.033), independent of changes in BMI and thyroid function. No significant change in nodule diameter was observed in the control group. However nodule count increased in both groups, no difference was found between them (p = 0.745).

conclusionsWe observed that BS was associated with a reduction in TSH and fT3 levels, progression of thyroid nodule diameter, and prevention of thyroid volume increase. To the best of our knowledge, this is the first study to evaluate nodule size changes post-BS versus controls.
