Validation of a tool for determining the clinical utility of stillbirth investigations.
Article in The Australian & New Zealand journal of obstetrics & gynaecology, 2023. 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
backgroundUp to 20% of all stillbirths and 45% of term stillbirths are currently classified as unexplained. Many of these stillbirths do not undergo currently recommended investigations. This may leave questions unanswered and not identify stillbirths with a recurrence risk in subsequent pregnancies.
aimsTo validate a new tool (Stillbirth Investigation Utility Tool) to identify the clinical utility of investigations in stillbirth and the inter-rater agreement on cause of stillbirth using the Perinatal Society of Australia and New Zealand-Perinatal Death Classification (PSANZ-PDC). MATERIALS AND
methodsThirty-four stillbirths were randomly selected for inclusion, each assessed independently by five blinded assessors. The investigations were grouped into three categories: clinical and laboratory; placental pathology; and autopsy examination. The cause of death was assigned at the end of each group. Outcome measures were clinical utility of investigations measured by assessor rated usefulness and inter-rater agreement on the assigned cause of death.
resultsComprehensive maternal history, maternal full blood count, maternal blood group and screen and placenta histopathology were useful in all cases. Clinical photographs were not performed and should have been performed in 50% of cases. The inter-rater agreement on cause of death assigned after all investigation results was 0.93 (95% CI 0.87-1.0).
conclusionsThe new Stillbirth Investigation Utility Tool showed very good agreement in assigning the cause of death using PSANZ-PDC. Four investigations were useful in all cases. Minor refinements will be made based on feedback to enhance usability for wider implementation in research studies to assess the yield of investigations in stillbirths.
