1 · What the graph read from it

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.

2 · The registry

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

An updated varicella case definition and classification from the Council of State and Territorial Epidemiologists became effective in 2024, emphasizing laboratory confirmation by requiring that confirmed cases be laboratory confirmed or epidemiologically linked to a laboratory-confirmed case, in addition to meeting clinical criteria. We assessed the impact of the changes using varicella reports in Minnesota from January 1, 2024, through May 31, 2025. Of 737 reports, 61.2% (n = 451) met the new definition and 61.9% (n = 456) met the old definition; 12.1% (n = 89) changed classifications. The proportion of cases classified as confirmed decreased by 17.5%, while those classified as probable increased by 28.0%; changes were primarily driven by the requirement to link reports to a laboratory-confirmed case. Reports not classified (ie, undefined; 26.9%; n = 198) mostly lacked rash descriptions. The updated definition improves jurisdictions' ability to classify cases accurately, thus strengthening national surveillance by reflecting current varicella epidemiology. Improved reporting of rash description, epidemiologic information, and increased laboratory testing are needed to improve surveillance.
