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

purposeThe aim of this study was to compare the clinical outcomes between laparoscopic partial liver resection and open partial hepatectomy for tumors in the posterosuperior segments.

methodsThe clinical outcomes of patients who underwent either laparoscopic (n = 20) or open (n = 44) resection in segments 7/8 of the liver were initially evaluated. Because of disparities in the background characteristics, a case-matched study (1:1) was conducted. In addition, a comparative study of the patients who met the institutional criteria for laparoscopic partial hepatectomy was performed.

resultsIn the case-matched study, the laparoscopic technique required a longer operation time (p = 0.001), but was associated with less intraoperative blood loss (p = 0.021), a lower incidence of major complications (p = 0.014), higher levels of serum albumin on postoperative days 3 and 7 (p = 0.031 and p = 0.035), and earlier discharge (p = 0.001) than open resection. The results of the latter study were similar to those of the case-matched analysis.

conclusionsLaparoscopic partial hepatectomy was a feasible procedure for treating tumors in the posterosuperior segments without compromising oncological safety and yielded better short-term outcomes than open techniques. In addition, this study provides concrete selection criteria for laparoscopic partial hepatectomy for difficult lesions.
