Modified APPEND Score for the Diagnosis of Acute Appendicitis in a New Zealand Pasifika Population.
Article in World journal of surgery, 2025. 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
backgroundDiagnosing acute appendicitis often requires biochemical and imaging support which may not be feasible in low- and middle-income countries (LMICs). The APPEND score, developed in New Zealand, includes C-reactive protein (CRP) which in resource-limited settings, may be hindered by slow processing times. This study aims to evaluate a modified APPEND score (mAPPEND), excluding CRP for diagnosing appendicitis in a New Zealand Pasifika cohort.
methodsThis secondary analysis utilized data from two cohorts (2011 and 2017) from Middlemore Hospital, Auckland. Patients aged ≥ 15 years with right iliac fossa pain for < 7 days were included, excluding those with prior appendicectomy or generalized peritonitis. Sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) were calculated, and diagnostic performance was assessed using receiver operating characteristic curve analysis, comparing the area under the curve (AUC) for both scores.
resultsAmong 143 Pasifika patients, the AUC for the APPEND and mAPPEND scores were comparable (0.84 vs. 0.85 respectively, p = 0.41). The mAPPEND score demonstrated high diagnostic accuracy with scores between 1 and 2 showing high sensitivity (100% and 97%) and NPV (90% and 92%), scores 4-5 showing high specificity (94% and 100%, respectively) and PPV (90% and 100%, respectively), and a score of 3 being the most efficient with a sensitivity of 82% and specificity of 71%.
conclusionThe mAPPEND score maintains high diagnostic accuracy for appendicitis in a New Zealand Pasifika population. This modified score is a simple and viable tool in settings where CRP testing is unfeasible, supporting its use in Pacific Island countries.
