The Effect of the Coexistence of Hair Follicle and Perforator Artery Density on Length of Hospital Stay in Burns.

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
Whilst total body surface area, burn depth and age are established determinants of hospital stay, the independent influence of the anatomical region's biological microenvironment remains unexamined. This study evaluates the association between regional perforator artery density, hair follicle density and LOS in patients with second-degree burns. A single-centre retrospective cohort study was conducted on 1593 patients with second-degree burns. An isolated single-region subgroup (n = 352) was analysed independently. Regional perforator and hair follicle density data were compiled from published anatomical references. Scald burns were the most common aetiology (78.3%), with a predominantly paediatric population (71.0% under 18 years). In the isolated burn subgroup, LOS differed significantly between anatomical regions. The lower extremity had the longest LOS (4.71 ± 4.35 days), whilst the perineum had the shortest (2.00 ± 1.73 days). Perforator density showed a strong negative correlation with LOS (Spearman rs = -0.900; p = 0.037), and hair follicle density demonstrated a strong trend. The head-neck region, with the highest combined density, had the shortest LOS (2.72 days); the lower extremity, with the lowest combined density, had the longest (4.71 days; post hoc p = 0.004). Regional perforator and hair follicle density are significant biological determinants of LOS in second-degree burns, independent of TBSA.
