1 · What the graph read from 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.

2 · The registry

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

backgroundMelasma is an acquired, common hyperpigmented disorder on the face. While many therapeutic approaches are available, their efficacy is moderate.

objectiveTo investigate the safety and efficacy of a cream containing herbal mixture for melasma.

methodsA total of 90 volunteers with melasma were enrolled in this randomized, double-blind, controlled clinical study, and they were randomly divided into three groups (A, B, and C). Patients in group A were treated with a cream containing herbal mixture, while groups B and C were treated with arbutin cream and placebo, respectively, twice daily for 12 weeks. Melasma area and severity index (MASI) score, melanin index (MI), erythema index (EI), changes in density of inflammatory cells, and adverse events were evaluated every 4 weeks.

resultsAlthough MASI scores declined significantly in both groups A and B (P < 0.05), a greater reduction was seen in group A (13.00-9.82 = 3.18 for group A; 12.65-10.84 = 1.81 for group B). Moreover, the cream containing herbal mixture, but not arbutin cream and placebo, significantly reduced EI and density of inflammatory cells after 12-week treatment (P < 0.05). No adverse reactions were observed in either group A or group C. In group B, two subjects experienced mild erythema and itching, which disappeared after stop using the arbutin cream.

conclusionThe cream containing herbal mixture is safe and effective for melasma.
