Assessment of severity and avoidability of adverse drug reactions in neonates: a reproducibility study of the Hartwig tool and LAAT.
Observational study in European journal of clinical pharmacology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
objectiveTools for classifying adverse drug reactions (ADRs) have not yet been validated in the context of the neonatal intensive care unit (NICU). The study aims to investigate the inter-rater reliability of the Hartwig tool and the Liverpool avoidability assessment tool (LAAT) in assessing the severity and avoidability of ADR cases in hospitalized neonates.
methodsAn observational and prospective study was conducted in the NICU of a maternity hospital in Natal, Brazil. The Hartwig tool and LAAT were employed to assess the severity and avoidability of ADRs, respectively. Three experienced clinical pharmacists independently assessed all ADR cases. Inter-rater reliability was measured using Cohen's kappa coefficient (k) with corresponding 95% confidence intervals (CI).
resultsAmong 79 ADR cases, the mean gestational age was 29.7 ± 4.4 weeks, and the birth weight averaged 1446.0 ± 1179.3 g. The assessment of ADR severity using the Hartwig tool revealed a significant overall correlation (overall k = 0.573; 95% CI 0.395 to 0.753) with exact agreement (EA) and extreme disagreement (ED) rates between evaluators of 86.5% and 2.5%, respectively. However, no statistically significant correlation was observed for determining avoidability using the LAAT (overall k = 0.017; 95% CI - 0.048 to 0.082), with an EA rate of 83.6% and ED rate of 10.1%.
conclusionThe Hartwig tool demonstrates good reproducibility among different evaluators in determining the severity of ADRs, unlike the LAAT for assessing avoidability.
