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

introductionCongenital Heart Disease (CHD) remains a major health challenge globally, with surgical interventions being the primary treatment modality for many defects. While advancements in cardiac surgery have improved survival rates, early postoperative complications continue to pose risks, particularly in settings with limited resources like Kenya. The study aimed to assess the rate of any early postoperative complications and identify factors associated with it in children after cardiac surgery at a tertiary care hospital in Nairobi, Kenya from 2019 to 2024.

methodsThis was an single-center retrospective study including children (< 18 years) who underwent cardiac surgery due to congenital heart disease at a tertiary care hospital in Nairobi, Kenya, over a 5-year period. Categorical variables were described as frequencies and percentages, while continuous variables were described as medians with interquartile ranges (IQR). Categorical variables were compared using chi-square or Fisher exact test and continuous variables compared using Mann-Whitney U test. Variables with p-value < 0.1 in the univariable analysis were included in the multivariable logistic regression, with p-value < 0.05 set as the level of significance. All analyses were performed using Rstudio version 4.5.1.

resultsA total of 97 children were included in the study. The median age in months was 25.0 (IQR: 8.5-67.5) and 50 (51.5%) were male. Patent ductus arteriosus, ventricular septal defect, and atrial septal defect were the predominant preoperative diagnoses. At least one early postoperative complication occurred in 52.6% (95%CI: 42.6% to 62.5%) of the children. Preoperative oxygen saturation (AOR: 0.92; 95%CI: 0.85-0.98, p = 0.021) and closed heart surgery (AOR:0.32; 95%CI:0.11-0.86, p = 0.027) were significantly associated with early postoperative complications.

conclusionThe study findings highlight gaps and opportunities in perioperative care of children undergoing congenital heart surgery at a tertiary care center in Kenya. Preoperative oxygen saturation and closed heart surgery were independently associated with reduced odds of early postoperative complications. These findings suggest that optimizing preoperative physiological status and further investigating the factors driving the association between surgical approach and outcomes may inform strategies to improve perioperative care in this setting.
