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

aimTo describe the first Italian experience with teplizumab administered under a compassionate use programme for adults with Stage 2 type 1 diabetes (T1D), and to evaluate its feasibility, safety and early metabolic outcomes in a real-life clinical setting outside formal clinical trials. MATERIALS AND

methodsThree adult women (aged 20-40 years) with Stage 2 T1D, identified through islet autoantibody screening and dysglycaemia assessment, received a 14-day intravenous course of teplizumab (Tzield) in a day-hospital setting. Infusions were managed by a multidisciplinary team with standardised pre-medication and monitoring. Clinical and laboratory parameters (vital signs, lymphocyte count, liver enzymes, HbA1c, C-peptide, continuous glucose monitoring metrics) were recorded at baseline and after 3 months.

resultsTreatment was overall well tolerated. One patient developed mild transient elevation of transaminases and lymphopenia, resolving spontaneously. A second patient experienced a 40% reduction in lymphocyte count without symptoms. The third developed a mild cytokine-release syndrome on Day 5, which resolved with supportive therapy but led to treatment discontinuation due to anxiety. At 3-month follow-up, all patients maintained stable glycaemic control and preserved β-cell function.

conclusionsTeplizumab administration under compassionate use proved feasible and safe in a real-life academic context, consistent with pivotal trial data. The experience underscores the importance of a structured multidisciplinary approach, integrating endocrinologists, anaesthesiologists, nurses and psychologists to optimise adherence, safety and patient engagement during early disease-modifying immunotherapy in presymptomatic T1D.
