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

backgroundAcute appendicitis (AA) is the most common acute abdominal condition in children. The rate of unplanned readmission within 30 days after appendectomy ranges from 4% to 13%, significantly increasing the healthcare burden and affecting patient outcomes. Identifying independent risk factors for readmission is crucial for optimizing management of high-risk pediatric patients; however, relevant evidence in the Chinese pediatric population remains limited.

methodsThis study employed a single-center retrospective cohort design, enrolling 5,016 pediatric patients who underwent appendectomy for AA at Wuhan Children's Hospital between July 2013 and February 2025. Perioperative variables were collected via the electronic medical record system, including demographic characteristics, inflammatory markers (WBC, CRP), surgical approach (laparoscopic/open), and appendicitis classification (complicated appendicitis /uncomplicated appendicitis). The primary outcome was unplanned readmission within 30 days after discharge following appendectomy. Multivariate logistic regression analysis was performed to identify independent risk factors (SPSS 27.0), with collinearity diagnostics to ensure model stability. Receiver operating characteristic (ROC) curve analysis was used to determine optimal cutoff values for continuous variables.

resultsThe overall readmission rate was 2.4% (118/5,016), with 17.8% (21/118) requiring reoperation. Primary readmission causes included intra-abdominal infection (39.8%), intestinal obstruction (36.4%), and surgical site infection(SSI) (17.8%). 71.2% of readmissions occurred within ≤ 14 days post-discharge (median: 11 days). Independent risk factors included open surgery (aOR = 6.92, 95% CI: 3.65-13.13, P < 0.001), CRP ≥ 53.36 mg/L (aOR = 4.28, 95% CI: 2.62-6.98, P < 0.001), complicated appendicitis (aOR = 1.56, 95% CI: 1.03-2.37, P = 0.037), and operative time > 63.5 min (aOR = 1.82, 95% CI: 1.25-2.66, P = 0.002).

conclusionOpen surgery, elevated CRP (≥ 53.36 mg/L), complicated appendicitis, and prolonged operative time are independent risk factors for readmission following pediatric appendectomy. For children exhibiting these high-risk characteristics, individualized discharge follow-up strategies (e.g., early outpatient evaluation, enhanced complication monitoring) are recommended to reduce readmission risk. Future research should develop predictive risk models and validate the effectiveness of intervention measures.
