Laparoscopic appendectomy for acute appendicitis is more favorable for patients with comorbidities, the elderly, and those with complicated appendicitis: a nationwide population-based study.

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
backgroundLaparoscopic appendectomy (LA) is not routinely performed for appendicitis because the costs associated with that procedure are higher than those for open appendectomy (OA). However, few studies have investigated the economic influence of LA and OA on specific subpopulations including the elderly, patients with comorbidities, and patients with complicated appendicitis. This population-based study was designed to investigate determinants of costs and hospital length of stay (LOS) for patients undergoing appendectomy. Furthermore, the differences in costs and LOS were compared between LA and OA for various subpopulations.
methodsInpatients who underwent LA or OA for appendicitis during the period 2001-2008 were identified from claims data obtained from Taiwan's National Health Insurance program. Costs and LOS were evaluated by multiple linear regression models for various subpopulations stratified according to age, number of comorbidities, and severity of appendicitis.
resultsBetween 2001 and 2008, 22,252 patients (13.3%) underwent LA and 14,4438 (86.7%) had OA. Age, comorbidity, and severity of appendicitis were determinants of costs and LOS for both LA and OA. Although the costs and LOS for appendectomy increased with age and number of comorbidities, a sharper increase was noted for OA patients. Laparoscopic appendectomy mildly decreased LOS at the expense of significantly higher costs for young patients, those without comorbidities, and patients with uncomplicated appendicitis. In contrast, compared with OA, LA was associated with comparable costs and reduced LOS for the elderly, patients with comorbidities, and those with complicated appendicitis. In addition, hospital mortality and readmission rates for postoperative complications did not differ significantly between LA and OA.
conclusionConsidering costs and LOS, patients older than 65 years, patients with comorbidities, and patients with complicated appendicitis benefit more from the laparoscopic approach for the treatment of appendicitis.
