Clinical Predictors of Time to Hospital Discharge in Children With New-Onset Diabetic Ketoacidosis in Zambia: A Retrospective Cohort Study.
Article in Endocrinology, diabetes & metabolism, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
BACKGROUND AND
aimsDiabetic ketoacidosis (DKA) at type 1 diabetes diagnosis is common in low-resource settings and associated with prolonged hospitalisation. We aimed to identify determinants of time to discharge among children with new-onset DKA in Zambia.
methodsWe conducted a retrospective cohort study of children aged 0-16 years with newly diagnosed T1DM and DKA at the University Teaching Hospital, Lusaka (2018-2023). The primary outcome was time to discharge (days). We used Kaplan-Meier with log-rank tests and Cox regression. To address proportional hazards (PH) violation, we fitted a stratified Cox model (stratified by HbA1c, vomiting and DKA severity) for PH validation and a granulated Cox model with DKA severity (mild, moderate, severe) to estimate independent effects. PH was verified using Schoenfeld residuals.
resultsAmong 353 children (mean age 8.3 years, SD 4.6), median stay was 5 days (IQR 4-8). Log-rank tests showed significant differences in discharge probability by DKA severity (χ
conclusionsDKA severity is the strongest independent predictor of prolonged hospital stay in children with new-onset DKA. Ketonuria is a useful bedside marker but lacks independent effect beyond severity. Infection independently predicts faster discharge. These findings could inform risk stratification and resource allocation in similar settings.
