Variables affecting clinical response to treatment of facial port-wine stains by flash lamp-pumped pulsed dye laser: the importance of looking beyond the skin.
Observational study in Lasers in medical science, 2014. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 11 papers, 6 of them syntheses that pooled 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.
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
The response of port-wine stains (PWS) to conventional laser treatment in adults is difficult to predict. To assess the influence of local or systemic hemodynamic variables on the clearance of PWS by using flash lamp-pumped pulsed (FLPP) dye laser. All consecutive patients ages 18 years or older undergoing laser treatment for a facial PWS were eligible. Laser sessions were scheduled every 8 weeks. All patients were evaluated based on a standard scale with four evaluation categories, from no or minimal improvement to total or almost total clearance. Clearance was achieved by 50.1 % (95 % confidence interval 35.6-64.7) of patients after a maximum of 15 treatment sessions. In multivariate analysis, increased age, a newly described Type III capillaroscopic pattern, and presence of lesions in dermatome V2 were all associated with a reduced clinical response to treatment. In a model restricted to demographic pattern and patient characteristics, arterial hypertension was also associated with a lower clinical response. A strong association was found between arterial hypertension and the Type III capillaroscopic pattern. Age, arterial hypertension, capillaroscopic pattern, and body location should be considered when planning laser treatment of PWS.
