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: Wound complications in direct anterior approach (DAA) total hip arthroplasty (THA) may differ by incision type. Bikini incisions may improve cosmesis and healing, minimizing panniculus effects while single-use soft tissue protectors may prevent damage from surgical instruments. This study compared wound complication rates in DAA THA with longitudinal incisions with and without a tissue protector, and bikini incisions. Methods: We retrospectively reviewed 925 primary DAA THAs performed via standard longitudinal incision (n = 444, 48.0%), bikini incision (n = 375, 40.5%), and longitudinal incision with a tissue protector (n = 106, 11.5%). Wound data included complication type, depth, and treatment, including return to the operating room (RTOR). Analyses included pairwise Fisher exact testing and multivariable regression, controlling for age, sex, body mass index, smoking, surgical indication, American Society of Anesthesiologists, operative time, and performing surgeon. Results: There were 37 (4.0%) wound complications-34 (3.7%) superficial wound issues (eg, dehiscence without deep infection) and 3 (0.3%) deep infections. Seven (0.8%) patients required RTOR, with no significant difference between cohorts. Compared to the standard longitudinal incision (6.5%), both the bikini incision (2.4%) and the tissue protector (0.0%) cohorts had fewer overall wound complications. When controlling for the performing surgeon, the bikini incision performed similarly to the standard longitudinal approach (adjusted Odds Ratio: 0.49; Conclusions: DAA THA demonstrates an excellent safety profile, with a low overall incidence of wound complications. While initial reductions in superficial complications with bikini incisions and tissue protectors were influenced by surgeon-specific factors, all techniques proved to be highly safe and effective, with low RTOR rates.
