Treatment Outcomes of Presacral Pilonidal Sinus Disease Using Crystallised Phenol: A Single-Centre Clinical Series.
Article in International wound journal, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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 evaluate short-term treatment outcomes and treatment burden in patients with presacral pilonidal sinus disease managed with crystallised phenol in a single-centre clinical series, with particular emphasis on the relationship between pit burden and session requirement.
methodsConsecutive patients treated with crystallised phenol were analysed (n = 40). Demographic and clinical characteristics, symptom duration, pit count, number of phenol sessions (2 vs. 3), inter-session intervals, and total treatment duration were recorded. All patients completed scheduled clinical reassessment at 5 weeks and 3 months. Treatment-related abscess and recurrence during follow-up were documented. Continuous variables are presented as mean ± standard deviation and median (minimum-maximum). Comparisons between the two-session and three-session groups were performed with the Mann-Whitney U test for continuous variables and Fisher's exact test for categorical variables.
resultsThe cohort was predominantly male (75%), with a mean age of 29.23 ± 9.85 years and a mean body mass index of 25.81 ± 3.85 kg/m
conclusionIn this single-centre series, crystallised phenol provided acceptable short-term outcomes and a relatively short treatment course in presacral pilonidal sinus disease. Pit count emerged as the main determinant of requiring a third session, whereas smoking status and BMI were not associated with session requirement. Larger studies with longer follow-up are needed to clarify predictors of recurrence and to determine whether higher session requirements simply reflect disease complexity or also influence outcome.
