Factors associated with complications among children and adolescents with sickle cell disease in a tertiary hospital in southwestern Nigeria.
Article in BMC pediatrics, 2026. 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
backgroundDespite Nigeria having the largest burden of sickle cell disease (SCD) globally, the spectrum of complications and associated factors remains an understudied area, with most studies focused on acute complications of vaso-occlusive crisis. Hence, we determined the spectrum of complications (acute and chronic) of sickle cell disease and the associated factors among Nigerian children and adolescents residing in southwestern Nigeria.
methodsThis cross-sectional descriptive study was conducted among children and adolescents with SCD in southwestern Nigeria from January 2021 to June 2022. We obtained relevant information from the caregivers and verified this using case record files and physical examinations to identify past or present evidence of complications.
resultsAmong the 100 children and adolescents recruited, 34 (34.0%) had at least one complication of SCD, 21 (61.8%) of whom were males. Osteomyelitis was the most common complication 20 (58.8%)] of 34 patients. The variables associated with complications were age, hospital admissions, total white blood cell count, and liver size. After adjusting for confounders, the variables associated with complications were adolescent age [adjusted odds ratio (AOR) of 7.8, 95% confidence interval (CI)] of 1.806-33.225, hepatomegaly of 2.0-5.0 cm with an AOR of 4.8 (95% CI of 1.199-18.782), and hepatomegaly greater than 5.0 cm with an AOR of 8.8 (95% CI of 1.989-38.676).
conclusionThis study revealed that one-third of SCD children and adolescents experienced at least one complication, and half experienced osteomyelitis. Being an adolescent and the presence of hepatomegaly increased the odds of complications of SCD.
