What is the impact of the UK soft drinks industry levy on childhood tooth decay?
Article in Evidence-based dentistry, 2024. 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
designInterrupted time series analysis. DATA ANALYSIS: An interrupted time series (ITS) analysis was conducted to determine if there was an association between the announcement and implementation of the soft drinks industry levy (SDIL) and rates of hospital admission for tooth extractions due to dental caries in children. Hospital Episode Statistics (HES) were used on hospital admissions for tooth extraction of one or more primary or permanent tooth due to a primary diagnosis of dental caries in children aged 0-18 years attending a National Health Service (NHS) hospital in England from January 2012 (pre-SDIL) to February 2020 (post-SDIL implementation). HES data were grouped and summarised by Index of Multiple Deprivation (IMD) and age group.
resultsThere was an absolute reduction of 3.7% (95% CI 5.3% to 2.2%) per 100,000 population/month and a relative reduction of 12.1% (95% CI 17.0% to 7.2%) in hospital admissions for carious tooth extractions in all children (0-18 years) compared if there had been no announcement of the SDIL (counterfactual scenario). Reductions were observed in children living in most areas regardless of the level of deprivation and most notably in the youngest children (<10 years).
conclusionsAn ITS analysis of administrative data on hospital admissions found the announcement of the UK SDIL was associated with improvements (reduction) in the incidence of hospital admissions for tooth extractions due to dental caries. This study provides evidence of benefits of the UK SDIL to children's oral health.
