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

introductionrecipients of monovalent rotavirus vaccine have a low risk of developing intussusception (IS) in high- to medium-high-income countries. In sub-Saharan Africa, Zambia included, this risk of IS has not been assessed. Two-dose monovalent rotavirus vaccine, introduced in Zambia in 2012 in the capital of Lusaka, and rolled out countrywide in 2013, is administered at 6 and 10 weeks of age with no catch-up dose. Active IS surveillance monitoring in children < 2 years has been ongoing in Zambia since July 2009 and additional retrospective review was conducted from 2007- June 2009.

methodsretrospective review (January 2007-June 2009) and prospective (July 2009-December 2018) IS surveillance was conducted at nine hospitals and four large paediatric hospital departments in Zambia, respectively. Demographic and clinical data were collected from medical folder abstraction and supplemented by parental interview during prospective surveillance.

resultsa total of 248 children < 2 years with IS were identified; 57.3% were male. Most cases with IS were infants (85.5%). IS admissions remained stable during the surveillance period with no seasonality pattern although an increase in cases occurred between August and October, hot dry season. The median time from symptom onset to presentation for treatment was 2 days and 63.6% (154/242) of IS diagnoses were made during surgery. The bowel resection rate was 46.6%. A high CFR of 23.3% was observed.

conclusionthe number of intussusception cases in Zambia was relatively small and remained stable over the 12-year study period. However, a high CFR was observed among cases.
