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

purposeSeveral reports have demonstrated the effectiveness and feasibility of single incisional transumbilical laparoscopic-assisted appendectomy (TULAA). We developed a modified TULAA technique, gasless-TULAA, which involves lifting the abdominal wall with a retractor, without pneumoperitoneum or another incision.

methodsWe assessed the surgical outcomes of 257 patients treated for appendicitis in our hospital between 2005 and 2013. In a preoperative comprehensive evaluation, appendicitis without abscess was defined as mild appendicitis (mild appendicitis group: MAG), and appendicitis with abscess was defined as severe appendicitis (severe appendicitis group: SAG). The clinical outcomes were compared with those in other published reports. The cost-effectiveness of gasless-TULAA was compared with that of conventional multiport laparoscopic appendectomy (CMLA) in our hospital.

resultsIn MAG (n = 228), the operation time and postoperative hospital stay were 46.9 ± 22.7 min and 2.6 ± 1.2 days, respectively. The gasless-TULAA was completed without trocars in 91.2 % of patients. The surgical outcomes of SAG were significantly worse than those of MAG (p < 0.001). The surgical cost of gasless-TULAA was significantly lower than that of CMLA (p < 0.001).

conclusionGasless-TULAA is a cost-effective, safe, and readily available surgical technique for mild appendicitis, which can obviate the need for specialized equipment.
