Association between phosphate and 30-day in-hospital mortality in paediatric ICU: a retrospective cohort study.
Article in BMJ paediatrics open, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundDeath rates in the intensive care unit (ICU) and paediatric ICU (PICU) are approximately 10.8% and 9.13%, respectively. Serum phosphate irregularities, such as low or high phosphate levels, significantly impact ICU patient outcomes. However, the connection between serum phosphate concentrations on admission and PICU mortality has not been investigated.
methodsInformation was collected from 12 881 PICU patients at the Children's Hospital, Zhejiang University School of Medicine, over an 8-year period from 2010 to 2018. The data were retrieved from the PIC database (http://pic.nbscn.org).
resultsA multiple linear regression model was used to assess associations between phosphate and 30-day PICU mortality, finding a significant positive relationship (OR 1.27, 95% CI 1.08 to 1.49). Generalised additive models were also developed, showing a non-linear association between serum phosphate and 30-day PICU mortality. In the two-phase linear regression analysis, the critical point for serum phosphate concentration was identified as 1.2 mmol/L. To the left of this point, serum phosphate levels were inversely correlated (OR 0.2, 95% CI 0.10 to 0.41), whereas to the right, a positive relationship was observed (OR 1.99, 95% CI 1.66 to 2.39).
conclusionsThe findings demonstrated a relationship between serum phosphate levels and 30-day PICU mortality. The relationship was represented by a U-shaped curve. Hypophosphataemia and hyperphosphataemia increased the risk of 30-day PICU death.
