Efficacy of photodynamic therapy in the short and medium term in the treatment of actinic keratosis, Basal cell carcinoma, acne vulgaris and photoaging: results from four clinical trials.
Article in Laser therapy, 2012. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers, 2 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
objectiveTo determine the clinical efficacy of methyl-aminolevulinate (MAL)-Photodynamic Therapy (PDT) in the treatment of actinic keratosis (AK), basal cell carcinoma (BCC), acne vulgaris (AV) and photoaging (PA), in the short and medium term. SUBJECTS AND
methodsFour separate prospective studies were designed on patients with AK (n=25), BCC (n=20), AV (n=20) and PA (n=25). Two PDT protocols were applied, and different clinical efficacy criteria were established, including lesion count and size. Two semi-quantitative and four analogue visual scales were completed for the evaluation of results according to the therapist, the patient and two independent experts.
resultsIn the AK and BCC studies, full clinical remission was observed in 84.7% and 75.7% of lesions, respectively. In the AV study, the number of inflammatory and non-inflammatory lesions fell significantly (p<0.001, p<0.05). In the PA study a reduction in Dover scale scores (3.19 vs. 2.14, p<0.001) was proven. The percentages of satisfied or very satisfied patients were: AK=88%, BCC=90%, AV=89% and PA=80%. A year later, none of the AK or BCC lesions had reappeared, and the cases of AV and PA remained stable, with a tendency towards improvement.
conclusionthe MAL-PDT procedures used produced efficacious, safe and satisfactory results in KA, BCC, AV and PA in the short and medium term.
