Factors associated with poor outcomes after congenital heart surgery in low-resource setting in Pakistan: insight from the IQIC Registry - a descriptive analysis.
Article in BMJ open, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
objectiveThis study aimed to assess the International Quality Improvement Collaborative single-site data from a developing country to identify trends in outcomes and factors associated with poor outcomes.

participantsPatients undergoing surgery for congenital heart disease (CHD). OUTCOME MEASURE: Key factors were examined, including preoperative, procedural and demographic data, as well as surgical complications and outcomes. We identified risk factors for mortality, bacterial sepsis and 30-day mortality using multivariable logistic regression.
resultsA total of 3367 CHD surgical cases were evaluated; of these, 59.4% (2001) were male and 82.8% (2787) were between the ages of 1 and 17 years. Only 0.2% (n=6) were infants (≤30 days) and 2.3% (n=77) were adults (≥18 years). The in-hospital mortality rate was 6.7% (n=224), and 4.4% (n=147) and 0.8% (n=27) had bacterial sepsis and surgical site infections, respectively. The 30-day status was known for 90.8% (n=3058) of the patients, of whom 91.6% (n=2800) were alive. On multivariable analysis, the adjusted OR for in-hospital mortality was 0.40 (0.29-0.56) for teenagers compared with infancy/childhood and 1.95 (1.45-2.61) for patients with oxygen saturation <85%. Compared with Risk Adjustment for Congenital Heart Surgery (RACHS-1) risk category 1, the adjusted OR for in-hospital mortality was 1.78 (1.1-2.87) for RACHS-1 risk category 3 and 2.92 (1.03-8.31) for categories 4-6. The adjusted OR for 30-day mortality was 0.40 (0.30-0.55) for teenagers and 1.52 (1.16-1.98) for patients with oxygen saturation <85%. The 30-day mortality rate was significantly higher in RACHS-1 risk category 3 compared with category 1, with an adjusted OR of 1.64 (1.06-2.55).
conclusionsWe observed a high prevalence of postoperative infections and mortality, especially for high-risk procedures, according to RACHS-1 risk category, in infancy/childhood, in children with genetic syndrome or those with low oxygen saturation (<85%).
