Changes in body mass index-z scores in 3-year-old children during the COVID-19 pandemic: a 2-year retrospective cohort study.

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
objectiveGiven how dramatically the pandemic has affected food systems, the economy, and the daily lives of children over the past 2 years, the potential impact of the pandemic on childhood obesity requires careful investigation. The aim of this study was to investigate the change in body mass index z-score in 3-year-old children and the inducing factors during the pandemic period.
methodsThe body mass index z-scores of all children participating in the study were calculated at the beginning of the pandemic (3-year-old body mass index z-score) and in its second year (5-year-old body mass index z-score).
resultsThis study, conducted during the 2-year pandemic period, found a strong association between the body mass index z-scores of children aged 3 and 5 years. The mean body mass index z-score increased between these time points for both boys and girls (p=0.013; p=0.034). In two different linear regression models created for the change in body mass index z score, gestational weight gain was found to be related. The regression coefficients (95% confidence intervals) and corresponding p-values were 0.580 (0.217-0.944) and p=0.002 for model 1, whereas they were 0.585 (0.217-0.961) and p=0.002 for model 2.
conclusionThis study showed an increase in body mass index z-scores in early childhood period during the COVID-19 pandemic. To prevent this increase, new strategies should be developed by considering the changes brought by the pandemic period.
