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

backgroundAppendectomy is one of the most common operations. Laparoscopic appendectomy (LA) is considered first-line treatment, but the use of LA for treatment of complicated appendicitis remains controversial. Here, we performed a retrospective analysis to compare clinical outcomes between patients treated with LA and those who underwent open appendectomy (OA).

methodsData for 179 patients who underwent an operation for the treatment of complicated appendicitis at our hospital between 2011 and 2017 were retrospectively analyzed. The selection included 89 patients who underwent a conventional appendectomy and 90 patients who were treated laparoscopically. Outcome measures such as mean operative time, blood loss, time until oral intake duration of hospital stay, and postoperative complications were analyzed. Logistic regression analysis was performed to determine the concurrent effects of the examined factors on the rate of postoperative complications.

resultsThe mean ages of patients in the OA and LA groups were 50.17 ± 22.77 and 50.13 ± 25.84 year. Mean operative times were longer in the LA group than OA (10.2.56 ± 44.4 versus 85.4 ± 43.11 min; p = 0.009). The duration of hospital stay was shorter for the LA group (9.61 ± 5.57 versus 12.19 ± 8.4; p = 0.016). There were no significant differences in return to consumption of oral intake between the LA and OA groups (2.03 ± 1.66 versus 2.48 ± 2.17; p = 0.123). Multivariable analysis found that the rate of postoperative complications was significantly reduced for the LA group, in comparison with the postoperative-complication rate of the OA group (16.7% versus 27%; odds ratio 0.376; 95% CI 0.153-0.923; p = 0.0327).

conclusionsThese results suggest that LA is a safe and efficient operative procedure that provides clinically beneficial advantages in comparison with OA. Thus, when possible, appendectomy for complicated appendicitis should be attempted using a laparoscopic approach.
