Metric Options: Counts1 Year3 YearSelecting 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.

Article Description
Le pica est généralement défini comme la consommation compulsive de produits non alimentaires sur une période prolongée, en dehors de tout contexte culturel. La consommation de glaçon ou pagophagie serait le type de pica le plus étroitement lié à la carence martiale. Nous avons étudié la prévalence des picas et leurs caractéristiques chez des sujets carencés en fer. Cette étude prospective unicentrique a été menée à la Réunion sur des individus venant en hôpital de jour pour une perfusion de fer, en raison d’une carence martiale chronique ou d’un saignement récent. Les patients étaient interrogés sur la présence de pica. Le lien entre la présence de pica et les données démographiques/clinico-biologiques était évalué en analyses univariée et multivariable. Notre échantillon comportait 426 femmes et 69 hommes, avec 112 picas (22,6 %), dont seulement deux chez les hommes. La pagophagie était le pica le plus fréquent (13,7 %). Il n’y avait qu’un seul cas de pica chez les patients avec hémorragie récente sans carence martiale chronique (1 %). L’analyse multivariable sur la présence de pica chez les femmes carencées en fer retrouvait comme seul facteur associé le jeune âge. Les facteurs associés à la pagophagie comparativement à un autre type de pica était le jeune âge et l’hémoglobine basse. Le pica, notamment la pagophagie, est un phénomène fréquent à rechercher à la Réunion chez les jeunes patientes carencées en fer ou susceptibles de l’être. Pica is a behavioral disorder generally defined as the compulsive consumption of non-edible substances for more than 1 month. The consumption of ice cubes or pagophagia is the type of pica the most closely linked to iron deficiency. We studied the prevalence of picas and their characteristics in iron deficient subjects. This is a single-center prospective study conducted in Reunion island on individuals coming to day hospitals for an iron intravenous infusion due to an iron deficiency or a recent bleeding. Patients were asked about the presence of pica and its characteristics. The links between pica and demographic/clinico-biological data were assessed in univariate and multivariable analyzes. Our sample included 426 women and 69 men, with a total of 112 picas (22.6 %) gathering only two men. Pagophagia was the most common pica (13.7 %). There was only one case of pica in patients with recent bleeding without pre-existing iron deficiency (1 %). In the multivariable logistic regression analysis regarding the presence of pica, the only factor associated with pica was a young age. In the second analysis, factors associated with pagophagia compared with another type of pica were a young age and a lower hemoglobin level. Pica, especially pagophagia, is a frequent phenomenon in young iron-deficient female patients in Reunion island.
