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

rationaleInsulin antibody-mediated insulin resistance is a rare autoimmune mechanism that can cause severe hyperglycemia. PATIENT CONCERNS: A 52-year-old male patient was admitted to our hospital with complaints of polydipsia, polyuria, and weight loss (8 kg in 6 months). He was diagnosed with type 2 diabetes mellitus at age 33. DIAGNOSES: Type 2 diabetes mellitus with antibody-mediated insulin resistance syndrome.

interventionsRituximab infusion in a 500 mg dose was given 2 times in a 2-week interval. OUTCOMES: A significant response was achieved 1 month later with fasting plasma glucose: 120 mg/dL (6.7 mmol/L), glycosylated hemoglobin A1c: 7.6% (59.6 mmol/mol), and anti-insulin antibodies: 0.001 U/mL. Clinically improved response persisted for about 6 months. LESSONS: Clinicians should be aware of the antibody-mediated insulin resistance, recognize suggestive signs and symptoms, pursue appropriate diagnostic evaluation, and treatment approach.
