[Off-label use of intravenous immunoglobulin g in a highly complex pediatric hospital in Argentina. A prospective observational study]

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
Introduction: The World Health Organization recommends prioritizing safe and effective drugs proven by clinical or epidemiological studies. However, in population groups with little research, a drug can be used for an indication or pharmaceutical form different from that approved by the regulatory agency (off-label), extrapolating data from studies in adults and exposing pediatric patients. to develop an Adverse Drug Reaction (ADR) due to safety considerations that have not been systematically studied. Intravenous immunoglobulin (IVIg), a high-cost drug, is used with scant evidence in some low-prevalence pathologies. This paper describes and analyzes the off-label use of IVIg at the J. P. Garrahan Pediatric Hospital. Methods: Observational, descriptive, prospective study on off-label indications of IVIg. The sampling technique was non-probabilistic and for convenience during 7 months. Results: 305 IVIg infusions were studied, corresponding to 111 patients. The indication classification showed that 22% (n=67) of the infusions were off-label. In neurology there was a higher percentage of off-label indications (46%) and within them 45% corresponded to the use in neurological disorders. 81% of the doses indicated off-label were in the range 0.8-1g/kg. The off-label infusions presented 61.5% (n=8) of the ADRs. Those from the Neurology service represented 87.5%; 75% being from the "Neurological disorders" group. Conclusion: In some cases, IVIg was indicated in an off-label manner, finding a statistically significant relationship with the appearance of ADR. This finding motivates the proposition of new hypotheses to carry out more studies.
