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

introductionRh sensitization occurs when Rh(D)-negative women develop anti-Rh(D) antibodies following exposure through pregnancy or transfusion. Rh disease may cause jaundice, anemia, neurological impairment, and death. It is rare in countries where Rh Immune Globulin (RhIg) is used. Canadian Rh sensitization and disease rates are unknown.

methodsThis survey-based study was conducted using a Canadian Paediatric Surveillance Program questionnaire sent to Canadian paediatricians and paediatric subspecialists to solicit Rh disease cases from May 2016 to June 2018. Paediatricians reported Rh-positive infants ≤ 60 days of age, born to Rh-negative mothers with RhD sensitization.

resultsSixty-two confirmed cases of infants affected by Rh(D) sensitization were reported across Canada. The median gestational age of neonates was term, age at presentation was 2 hours, and hemoglobin at presentation was 137.5 g/L (33 to 203 g/L). The median peak bilirubin and phototherapy duration were 280 µmol/L (92 to 771 µmol/L), and 124 hours, respectively. Thirty (48%) infants received Intravenous immune globulin (IVIG) (median two doses). Seventeen (27%) received one to three simple transfusions; 10 (16%) required exchange transfusions. Six (10%) infants presented with acute bilirubin encephalopathy, and less than five presented with seizures. Fourteen mothers with affected infants were born outside of Canada. DISCUSSION: Rh disease continues to exist in Canada. Additional efforts are needed to raise awareness of Rh disease, prevent disease, and minimize sequelae when it does occur. The ongoing global burden of Rh Disease, as well as the possibility of emerging Rh immunoglobulin refusal are among factors that could be taken into consideration in future prevention efforts.
