Respiratory Outcomes at 5-Year Follow-Up in Children with Mannose-Binding Lectin Deficiency: A Retrospective Cohort Study.
Article in Thoracic research and practice, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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.
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
objectiveMannose-binding lectin deficiency may predispose children to having increased infection susceptibility. However, there is no conclusive evidence that mannose-binding lectin deficiency is associated with adverse respiratory consequences in children. We aimed to evaluate the effects of mannose-binding lectin deficiency (defined as a level of less than 0.6 mg/L) on clinical, radiological, and microbiological characteristics in children presenting with troublesome respiratory symptoms, as compared to those who are mannosebinding lectin-sufficient. MATERIAL AND
methodsWe conducted a retrospective cohort study to investigate the association between mannose-binding lectin deficiency and respiratory outcomes in children over a period of 10 years in a large teaching hospital. Children presenting with frequent or persistent respiratory symptoms such as a chronic wet cough lasting more than 4 weeks, recurrent lower respiratory tract infections (≥4 infections in a year), or severe respiratory tract infections requiring admission to intensive care or to high dependency unit were included in the study.
resultsThe study showed no significant difference in clinical outcomes with mannose-binding lectin deficiency and sufficiency. Thirty-two percent of children with mannose-binding lectin deficiency and 30% of those with mannose-binding lectin sufficiency had positive respiratory microbiology. Twenty-three percent of children with mannose-binding lectin deficiency and 24% of those with mannose-binding lectin sufficiency had radiological changes on plain radiographs; also the prevalence of bronchiectasis was similar in both groups. The rates of admission to pediatric intensive care unit were comparable in the 2 groups.
conclusionsChildren with mannose-binding lectin deficiency and sufficiency showed similar clinical, radiological, and microbiological characteristics. Our study suggests that there are no childhood adverse respiratory consequences with mannose-binding lectin deficiency.
