Development of a nomogram for prediction of postoperative sore throat in patients under general anaesthesia: a single-centre, prospective, observational study.
Observational study in BMJ open, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT06191783 (The Effect Of Preoperative Anxiety Level On Postoperative SoreThroat In Tympanoplasty Patients), which is not on this map. Cited by 6 papers.
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.

Abstract
objectivesPostoperative sore throat (POST) is very common in patients under general anaesthesia. However, there is no effective clinical predictive model for reducing its occurrence. The objective of this study was to estimate the risk factors for POST in patients after general anaesthesia by designing a nomogram.
designA prospective study.
settingThis study was conducted in a large tertiary hospital.
participantsPatients aged 18-85 years old who received general anaesthesia with either an endotracheal tube or supraglottic airway and of American Society of Anesthesiologists classification level Ⅰ-III.
resultsA total of 442 patients were enrolled in this study, with a POST incidence of 44.1%. The results showed that younger age (≤55 years), surgical site (head and neck surgery), duration of anaesthesia (≥4 hours) and history of chronic pharyngitis were independent risk factors for POST in general anaesthesia patients. Receiver operating characteristic (ROC) curves and calibration curves were used to evaluate the nomogram. The area under the ROC curve was 0.784 and the C-index was 0.779.
conclusionA nomogram combining age, surgical site, duration of anaesthesia and history of chronic pharyngitis is potentially useful in predicting POST under general anaesthesia. TRIAL REGISTRATION NUMBER: ChiCTR-ROC-17013258; Post-results.
