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
backgroundMedication-overuse headache (MOH) is a significant secondary headache that interferes with existing primary headache conditions, yet it is often an overlooked condition. This study aimed to develop and validate a user-friendly self-administered questionnaire to screen for MOH, to enhance early detection, an essential first step in the MOH care cascade in Thailand. MATERIALS AND
methodsA Thai-language Self-Screening Questionnaire of MOH (SSQ-MOH) was developed to screen for MOH based on the International Classification of Headache Disorders, 3rd edition (ICHD-3), the Leeds Dependence Questionnaire, and the Severity of Dependence Scale. The questionnaire underwent iterative refinement through expert consultation with four headache specialists, patient feedback, and linguistic adjustments. The final questionnaire was launched, and data were collected from headache patients attending the specialized tertiary Headache Clinics, King Chulalongkorn Memorial Hospital, Bangkok, Thailand. Items in the questionnaire were selected and optimized to maximize sensitivity and specificity, using the final diagnosis made by headache specialists according to ICHD-3 criteria as the gold standard. Performance analysis-including sensitivity, specificity, predictive values, and the area under the receiver operating characteristic curve (AUC-ROC)-was conducted for each item individually. A combination of items was selected based on their individual AUC-ROC values.
resultsAmong the 94 patients included (89.4% female; median [IQR] age: 38 [29.0-52.0] years), the most common primary headache disorder was migraine (87.2%, n = 82). MOH was diagnosed in 17 patients (18.1%). A combination of two items-"Q1: In the past month, have you experienced headache on at least 15 days?" and "Q2: In the past month, have you taken headache painkillers on at least 10 days?"-with both answered demonstrated the highest diagnostic accuracy, with a sensitivity of 88.3%, specificity of 90.9%, and an AUC-ROC of 0.90.
conclusionThe SSQ-MOH demonstrates high sensitivity and specificity in headache clinic settings, supporting its utility as an effective screening tool. Further validation in various clinical settings in Thailand and other languages is needed.
