Metric Options: CountsSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Pandemic did not affect Cda’s preterm and stillbirth rates: study
New research has revealed that the COVID-19 pandemic did not not have an effect on the rates of preterm or stillbirths happening in Canada. A
Article Description
Several studies have documented changes in the rates preterm birth and stillbirth during the COVID-19 pandemic. We carried out a study to examine obstetric intervention, preterm birth, and stillbirth rates in Canada from March to August 2020. The study included all singleton hospital deliveries in Canada (excluding Québec) from March to August 2020 (and March to August for the years 2015–2019) with information obtained from the Canadian Institute for Health Information. Data for Ontario were examined separately because this province had the highest rates of COVID-19 in the study population. Rates and odds ratios with 95% confidence intervals (CIs) were used to quantify pregnancy-related outcomes. There were 136,445 and 717,905 singleton hospital deliveries in Canada (excluding Quebéc) in from March to August 2020 and between March and August 2015–2019, respectively. Rates of obstetric intervention declined in early gestation in 2020. Odds ratios for labour induction and cesarean delivery at <32 weeks gestation for March–August 2020 versus March–August in 2015 to 2019 were 0.84 (95% CI 0.74–0.95) and 0.92 (95% CI 0.85–1.00), respectively. Preterm birth rates increased in Canada (excluding Québec) from 6.42% in March–August 2015 to 6.74% in March–August 2019 but were unchanged in March–August 2020 (6.74%). Stillbirth rates were stable between March–August 2015 and March–August 2020. However, stillbirth rates peaked in Ontario in April 2020 due to higher rates of stillbirths at 20–27 and 37–41 weeks gestation. Changes in labour induction and cesarean delivery at early gestation and other perinatal outcomes during the period of March to August 2020 highlight the need to reconsider the use and impact of obstetric services in pandemics as well as the need for timely perinatal surveillance. Plusieurs études ont fait état des changements des taux d'accouchements prématurés et de mortinaissances pendant la pandémie de COVID-19. Nous avons mené une étude pour examiner les taux d'interventions obstétricales, d'accouchements prématurés et de mortinaissances au Canada pour la période de mars à août 2020. L’étude comprend tous les accouchements de grossesses monofœtales au Canada (Québec exclu) pour la période de mars à août 2020 (et pour la période de mars à août en 2015-2019) d'après les données obtenues auprès de l'Institut canadien d'information sur la santé. Les données pour l'Ontario ont été examinées séparément, car cette province avait le plus haut taux de COVID-19 dans la population à l’étude. Les taux et les rapports de cotes avec les intervalles de confiance (IC) à 95 % ont été utilisés pour quantifier les issues liées à la grossesse. Au Canada (Québec exclu), il y a eu 136 445 accouchements de grossesses monofœtales en milieu hospitalier pour la période de mars à août 2020 et 717 905 pour la période de mars à août en 2015-2019. Le taux d'interventions obstétricales à un âge gestationnel précoce a diminué en 2020. Les rapports de cotes pour le déclenchement artificiel du travail et la césarienne avant 32 SA étaient de 0,84 (IC à 95 % : 0,74-0,95) pour la période de mars-août 2020 et de 0,92 (IC à 95 % : 0,85-1,00) pour la période de mars-août en 2015-2019. Le taux d'accouchements prématurés a augmenté au Canada (Québec exclu), passant de 6,42 % en mars-août 2015 à 6,74 % en mars-août 2019, mais est demeuré stable en mars-août 2020 (6,74 %). Le taux de mortinaissances est demeuré stable entre mars-août 2015 et mars-août 2020. Cependant, le taux de mortinaissances a atteint un sommet en Ontario en avril 2020 en raison de l'augmentation du taux de mortinaissances à 20-27 SA et à 37-41 SA. Les changements relatifs au déclenchement artificiel du travail et à la césarienne à un âge gestationnel précoce ainsi qu'aux autres issues périnatales pendant la période de mars à août 2020 mettent en évidence la nécessité de réévaluer l'utilisation et les conséquences des services obstétricaux en temps de pandémie de même que la nécessité d'exercer une surveillance périnatale en temps opportun.
