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
Background: Hypertrophic scars and keloids can develop from surgical incisions. These pathologic scars grow progressively due to chronic dermal inflammation, which is exacerbated by skin tension. Postsurgical wound tension can be mitigated by various surgical tactics. One underrecognized aspect is surgical incision orientation. Here, we discuss the principles underlying existing surgical incision line systems, including Langer and Pinkus lines, and propose a new system based on our observations of pathological scar growth. Methods: We review the biological mechanisms that drive pathological scar growth, describe existing surgical incision line systems and their limitations, and propose our "ideal surgical incision line" system. Results: Keloids grow in the direction of predominant skin-stretching tension. The main surgical incision line systems are those of Borges (relaxed skin tension lines caused by anatomical features), Kraissl (dynamic lines driven by muscle contraction), and Lemperle (striae distensae). Borges lines only consist of static lines; Kraissl lines are generally not accurate for dynamic wrinkles caused by multidirectional or multilayered muscle contraction; and not every patient bears striae distensae. Our experience with pathologic scars led us to develop an "ideal surgical incision" system for the face and entire body that incorporates static wrinkles, dynamic wrinkles caused by simple and multidirectional muscle contraction, and classical folds/creases/grooves. We also propose that when ideal lines cannot be used for practical reasons, Z-incisions and Z-plasties can mitigate skin tension. Conclusions: Our ideal surgical incision line system may help guide surgeons in their choice of surgical incision lines, thus reducing the risk of pathological scarring.
