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

objectiveTo evaluate and describe the changes in the therapeutic approach to Graves' disease at a tertiary hospital center over a 20-year period, with an emphasis on the frequency of prescription and the timing of radioactive iodine indication. SUBJECTS AND

methodsWe conducted a retrospective analysis of data from medical records of patients recently diagnosed with Graves' disease (GD) and followed up at a single institution during two consecutive periods: Group A diagnosed between 2002 and 2010, and Group B between 2011 and 2022. We analyzed the percentage of patients who underwent iodine therapy and were considered to have failed therapy if they did not achieve hypothyroidism or euthyroidism, comparing the results between both groups.

resultsA total of 597 GD patients were included, of which 223 underwent radioactive iodine (RAI) therapy (37.35%). In Group A, 176 patients (64%) received RAI treatment, whereas, in Group B, only 47 patients were given this therapeutic indication (14.6%) (p < 0.001). The reduction in RAI prescriptions between both periods was independent of the therapeutic indication. Interestingly, RAI prescription due to relapse after clinical treatment was uncommon in both study groups. There was a significant increase in the duration of antithyroid drug (ATD) therapy before RAI prescription in Group B compared to Group A.

conclusionSignificant changes were observed in GD treatment, with a decline in the use of RAI as a first-line or salvage therapy. Nonetheless, radioiodine therapy remained an effective and safe treatment modality with successful cure rates.
