Evaluating the accuracy of International Classification of Disease Perinatal Mortality (ICD-PM) codes assigned on death certificates before and after expert panel review: a mixed methods observational study.
Observational study in BMC pregnancy and childbirth, 2024. 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
introductionThe present study was conducted with the aim of evaluating the accuracy of International Classification of Disease Perinatal Mortality (ICD-PM) codes assigned on death certificates before and after an expert panel review.
methodThe present study was a mixed methods observational study conducted at Umm al-Benin Hospital, the sole specialized obstetrics and gynecology center affiliated with Mashhad University of Medical Sciences. The study comprised three distinct stages: (1) Collecting primary ICD-PM codes assigned to perinatal death certificates, along with other relevant information, from October 2021 to March 2022; (2) Examining the circumstances of each perinatal death case and re-identifying the causes of death through a consensus process involving a panel of experts comprising pediatricians, obstetrics and gynecology specialists, and nursing and midwifery experts; presenting the new ICD-PM code; (3) Comparing the ICD-PM codes assigned to perinatal death certificates before and after the expert panel's evaluation.
resultDuring the study period, a total of seven specialized panels were conducted to examine perinatal deaths. Out of the 71 cases, 41 were carefully reviewed by experts. These cases included 32 stillbirths and nine neonatal deaths. The examination process followed specific inclusion and exclusion criteria. The findings revealed that there were no significant changes in the causes of neonatal deaths. However, it was notable that 80% of the previously unknown causes of stillbirths were successfully identified. Notably, the occurrence of stillbirths increased by 78% due to maternal causes and conditions.
conclusionConvening panels of experts to discuss the causes of perinatal deaths can effectively reduce the percentage of unknown causes, as classified by ICD-PM. This approach also guarantees the availability of essential data for implementing effective interventions to decrease preventable perinatal deaths.
