Is Hair Removal Necessary after Crystallized Phenol Treatment in Pilonidal Disease?

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
objectiveThe most important cause of posttreatment recurrence of pilonidal sinus disease (PSD) is the reentry of hair into the skin. The study aimed to investigate the effect of hair removal and its duration on the prevention of recurrence after crystallized phenol treatment. SUBJECT AND
methodsPatients with PSD who were treated with crystallized phenol treatment were evaluated. Hair in the sacrococcygeal area was removed with depilatory cream before every crystallized phenol procedure, during the treatment, and after treatment once a month for 6 years. Of 1,016 patients, 735 were contacted by telephone or e-mail regarding the frequency of sacrococcygeal hair removal and recurrence. Demographic and sinus features and crystallized phenol application data of patients treated with crystallized phenol for PSD, as well as recurrences were retrospectively assessed.
resultsThe mean follow-up time was 46.23 ± 33 (range, 11-240) months, with 139 (18.9%) patients experiencing recurrence. Patients who underwent hair removal experienced significantly less recurrence than those who did not (p = 0.003, odds ratio [OR]: 0.54 [95% CI: 0.36-0.82]). The OR of recurrence decreased by 0.8% every month as the hair removal time increased (OR: 0.992, 95% CI: 0.985-1.000, p = 0.049). The cutoff value for sensitivity was 0.636, specificity 0.466, and area under the curve 0.562 in hair removal procedures that lasted for over 30 months.
conclusionRegular hair removal during, and at least 30 months after, crystallized phenol treatment reduced recurrences in patients with PSD.
