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

backgroundMultisystem inflammatory syndrome in children (MIS-C) is a severe postinfectious complication of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, primarily affecting children 6-12 years of age. Although MIS-C was prominent during the early pandemic waves, recent studies suggest a declining incidence concurrent with increasing reinfection rates. The objective was to determine whether the risk of MIS-C differs following a primary SARS-CoV-2 infection versus reinfection.

methodsA retrospective, multicenter, international, matched case-control study was conducted from September 1, 2021, to April 30, 2022. MIS-C cases were recruited from 14 French and Swiss hospitals. Eligible cases included children younger than 18 years meeting the 2020 World Health Organization case MIS-C definition with laboratory evidence of SARS-CoV-2 infection. Cases were matched 1:1 by age, sex and epidemic period to controls with laboratory-confirmed acute SARS-CoV-2 infection. Vaccinated patients and those without consent were excluded. The primary outcome compared the association of reinfection with MIS-C versus acute infection using McNemar's test to estimate matched odds ratios (ORs). Prespecified sensitivity analyses used conditional logistic regression.

resultsThe matched cohort included 180 MIS-C cases (median [IQR] age, 106 [62-136] months) and 180 controls (median [interquartile range] age, 72 [48-108] months). No MIS-C cases had a documented reinfection, whereas 3.9% (7/180) of controls did (McNemar χ 2 = 5.142; P = 0.023; matched OR, 0.067; 95% confidence interval [0.004-1.167]; P = 0.064). Sensitivity analysis also suggested a lower odds of MIS-C after reinfection without reaching statistical significance (adjusted OR, 0.183; 95% [0.027-1.234]; P = 0.093).

conclusionMIS-C occurred predominantly after first SARS-CoV-2 infections; while evidence for a lower risk following reinfection was suggestive but not conclusive.
