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

backgroundGastrointestinal perforation peritonitis is a life-threatening surgical emergency with high mortality. Early identification of patients at increased risk of poor outcomes is critical for optimizing care. In this study, we aimed to evaluate the prognostic value of combining serial Acute Physiology and Chronic Health Evaluation II (APACHE II) scores and serial serum lactate levels in predicting 30-day postoperative mortality among patients undergoing emergency laparotomy for gastrointestinal perforation peritonitis.

methodsIn this prospective cohort study, 120 adult patients diagnosed with gastrointestinal perforation peritonitis and undergoing emergency laparotomy were enrolled after obtaining ethical approval and informed consent. APACHE II scores and serum lactate levels were recorded at three time points: preoperatively (baseline), 6 h postoperatively, and 24 h postoperatively. The primary objective of this study was a combination of serial APACHE II and serial serum lactate level (baseline, 6 h and 24 h post-operatively) and its correlation with post-operative mortality in emergency laparotomy for hollow viscus perforation peritonitis. Data were analysed to compare clinical variables between survivors and non-survivors. Receiver operating characteristic (ROC) curves and area under the curve (AUC) analyses were used to assess the predictive performance of individual and combined markers.

resultsThe 30-day postoperative mortality rate was 35%. Significant differences in age, serial APACHE II scores, and serial serum lactate levels were observed between survivors and non-survivors. A serum lactate level of ≥ 1.88 mmol/L had a sensitivity of 81% and specificity of 69.2% (AUC: 0.817; p = 0.0001). APACHE II scores of ≥ 11.16 yielded a sensitivity of 76.2% and specificity of 91% (AUC: 0.915; p = 0.0001). Both serial lactate levels and APACHE II scores were independent predictors of 30-day mortality. The combination of serial APACHE II scores and serum lactate (cutoff ≥ 11.95) had a sensitivity of 85%, specificity of 82%, and an AUC of 0.919 (p = 0.0001), making it the preferred predictor for 30-day post-operative mortality.

conclusionsThe combination of serial APACHE II scores and serial serum lactate levels provides superior prognostic accuracy for predicting 30-day postoperative mortality in patients undergoing emergency laparotomy for gastrointestinal perforation peritonitis. This approach may facilitate early identification of high-risk patients and guide clinical decision-making.
