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
Importance: Port-wine stain (PWS) is a congenital vascular condition involving dilation of skin capillaries and venules, significantly affecting patients' physical and mental health. Pulsed dye laser (PDL) is widely used for PWS treatment; however, large-scale data on pediatric cases remain limited. This retrospective study aims to investigate the efficacy of laser treatment and its related factors in a large sample. Objective: To assess the clinical efficacy and adverse reactions of 595nm PDL for treating pediatric PWS and to identify factors influencing treatment outcomes. Methods: This retrospective study included 974 pediatric patients with PWS treated at Beijing Children's Hospital from 2003 to 2021. Inclusion criteria required patients to be under 18, with solitary PWS and Fitzpatrick skin types II-IV. Treatment efficacy was evaluated using standardized photographs taken before and after treatment, with outcomes categorized by Achauer's clearance criteria. Ridit analysis assessed the impact of variables such as gender, age, lesion location, and treatment frequency on outcomes. Results: The overall efficacy rate was 65.3%, higher in females (69.7%) than males (59.7%). Adolescents had the highest efficacy (100%) due to better compliance. Limb lesions responded best (87.5%), followed by neck (75.0%), trunk (66.7%), and head/face (63.0%). Smaller lesions (≤3 cm²) achieved 76.8% efficacy. Efficacy rose with sessions, reaching 84.0% after three. The mandibular branch (V3) had the highest trigeminal efficacy (68.5%). Adverse reactions (4.31%) included pigmentation changes (2.87%), hypopigmentation (1.03%), and minimal scarring (0.41%). Conclusion: The efficacy of 595nm PDL for treating PWS in children is influenced by gender, age, lesion location, size, and the number of treatment sessions. PDL is an effective treatment for pediatric PWS with minimal adverse reactions.
