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

introductionAgranulocytosis is a rare but serious complication of methimazole (MMI) use for Graves' disease (GD). Treatment requires discontinuation of MMI, and the use of propylthiouracil (PTU) is also contraindicated. Few reports exist about the optimal alternative treatment regimens for the management of thyrotoxicosis in these medically complex patients in the pediatric population. CASE REPORT: We report prolonged saturated solution of potassium iodide (SSKI) use (29 days) in a 17-year-old female with GD and MMI-induced agranulocytosis, who presented with septic shock. Her treatment course also included β-blockade, cholestyramine, and granulocyte colony stimulating factor. We performed a review of the literature on the use of SSKI in the management of thyrotoxicosis, as well as best practices from the view of endocrinology, infectious disease, hematology, surgery, and intensivists, for the evaluation and management of MMI-induced agranulocytosis. DISCUSSION: The management of MMI-induced agranulocytosis and associated sequelae require subspecialty input and intensive evaluation and monitoring. Alternative treatments to manage hyperthyroidism and control symptoms of thyrotoxicosis during agranulocytosis are a bridge to definitive therapy and include β-blockade, SSKI, cholestyramine, steroids, lithium, and plasmapheresis.
