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

Background: We investigated whether the standardized "can-opener method" surgical technique is an adequate surgical procedure for hemispheric hepatectomy in segments 7 and 8. Methods: Forty-two patients who underwent laparoscopic hemispheric liver resection for segments 7 and 8 using our standardized surgical technique were enrolled. To examine the effect of this standardized surgical procedure on short-term outcomes, patients were classified into two groups based on the timing of the standardization of their procedures (Group A, the first half of the cases, and Group B, the second half of the cases). Short-term outcomes were subsequently compared between the two groups. Results: Significant differences in operation time (465 min vs. 332 min, Conclusion: Our standardized surgical technique is an adequate surgical procedure for hemispheric hepatectomy in segments 7 and 8 and is referred to as the "can-opener method".
