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

Background: Infectious diseases are frequent and sometimes deadly in sickle cell disease (SCD) patients. Some of these infectious diseases could be avoided through immunisation, but an immunisation schedule for children with SCD is not available in Gabon. Aim: This study looked into the determinants of immunisation in children with SCD in Libreville. Setting: This work was performed in five healthcare facilities in Libreville. Methods: A cross-sectional study on knowledge, attitudes, and practices was conducted from February 2019 to September 2019 in Libreville healthcare facilities, targeting children under 18 years with SCD. Results: A total of 172 parents of children with SCD participated. The average age of children was 7.1 ± 4.2 years, with a sex ratio of 1:36. Immunisation status was considered complete for 87.9% (95% CI = 79.8-93.1) according to the Expanded Programme of Immunisation (EPI) schedule. Only 49 (28.5%) parents understood SCD complications, and 39 (22.7%) knew how to prevent them. Immunisation coverage was better for children near public health centres ( Conclusion: Immunisation coverage of children with SCD was better than the national immunisation coverage in Gabon. Contribution: This study unravels the need for Gabon to improve its immunisation programmes in public healthcare facilities.
