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.
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
Diabetes is a prevalent disease in modern society. Since the development and widespread use of synthetic insulin, its therapeutic application has become globally recognized for managing diabetes. However, excessive administration of insulin may lead to fatal outcomes. The rapid pharmacokinetics of insulin in the human body, combined with the lack of distinct pathological changes, makes the forensic identification of fatal insulin overdose challenging. In this study, we present two cases of fatal insulin overdose, one with a postmortem interval of up to 28 days. Postmortem specimens were collected and analyzed. Immunohistochemical and immunofluorescence assays revealed the consistent distribution of insulin and protamine at the injection sites in both cases. Insulin and protamine particles were observed in the epidermis, epidermal cells, adipocyte membranes, inter-adipocyte spaces, inflammatory cells, and glandular structures. Toxicological analyses confirmed the presence of insulin in the injected skin, subcutaneous fat, blood, urine, vitreous humor, and bile. This study provides valuable insights and guidelines for the forensic identification of insulin overdose cases.
