Modelling Impact of Different Varicella Immunisation Strategies Upon Introduction in the Swedish National Programme.

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
aimCountries with varicella immunisation programmes have seen major reductions in disease burden. While two-dose schedules are now universally adopted, dosing ages vary, and some countries initially include catch-up vaccination of older children to speed impact. This modelling study assessed three two-dose schedules in the Swedish setting (1) 12 and 18 months, (2) 18 months and 5 years, and (3) 18 months and 7 years, with and without catch-up of susceptible children based on their medical history.
methodsA deterministic, compartmental, age-structured, dynamic transmission model was used to evaluate the different strategies.
resultsWith coverage similar to other childhood vaccinations in Sweden (≥ 95%) but no catch-up, varicella cases are projected to decrease significantly within four years of programme start for all schedules modelled. However, a temporary rebound may occur around years 4-7 due to accumulating susceptibles before subsiding. Adding catch-up vaccination in this high-coverage setting accelerates and sustains the decline, with varicella disease burden significantly reduced within 2-3 years.
conclusionA national childhood varicella programme in Sweden could cut transmission and disease burden within 4 years, with catch-up vaccination speeding this to a few years and lowering rebound risk. The schedule should be guided by programmatic considerations.
