Effects of Oral Isotretinoin on Taste and Olfactory Functions in Acne Vulgaris: A 6-Month Follow-Up Study.

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
introductionAcne vulgaris is a common multifactorial inflammatory skin disease of the pilosebaceous unit. Oral isotretinoin is one of the most effective choices among available treatments, and the most common and known side effects are mucocutaneous changes. However, few studies have investigated the smell and taste functions secondary to nasal and oral mucosal alterations.
objectiveThis study aimed to evaluate the changes in taste and smell functions before and after systemic isotretinoin treatment during a six-month period.
methodsThe study included 48 patients with acne vulgaris aged over 18 years who were indicated for treatment with isotretinoin. Taste and smell functions were measured in patients at three different time points: before treatment, at the third month, and at the sixth month of treatment.
resultsAmong 48 patients, 35 (72.9%) were female, and 13 (27.1%) were male. The mean age was 21.02 ± 3.42 years. The mean dose was 0.56 ± 0.08 mg/kg. The median taste scores were 14.5 (11-16) before treatment, 13.0 (10.5-16) at the third, and 12.0 (9-14) at the sixth month of therapy (P<0.001). A positive correlation was found between the decrease in taste scores and the mean dose (r=0.418, P=0.003). No significant change was observed in olfactory scores (P>0.05).
conclusionsAlthough isotretinoin is known to be a safe and effective treatment method for acne vulgaris, informing patients about changes in taste functions before starting the medication and during follow-up visits could make a significant difference in their quality of life.
