Clinical predictors for perioperative anticipated and unanticipated difficult intubation: a matched case-control 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
We aimed to determine the clinical predictors of perioperative anticipated and unanticipated difficult intubation using a matched case-control study. We recruited patients undergoing surgery with endotracheal intubation from 2015 to 2020. Difficult intubation was defined as at least 3 attempts to perform intubation with conventional or video laryngoscopy before surgery. Controls were randomly selected in a ratio of 3:1 matching on year of surgery, site of operation and age within 5 years. Clinical predictors were evaluated. A multivariate conditional logistic regression analysis was performed and presented with adjusted odds ratios (OR) and 95% confidence intervals (CI). We selected 168 cases and 504 controls out of 62,111 intubated patients. The predictors for anticipated difficult intubation were previous history of difficult airway (OR [95% CI]: 6.4 [1.3,32.5]) and abnormal facial appearance/syndrome (OR [95% CI]: 6.1 [1.3,28.0]). The predictors of unanticipated difficult intubation were BMI < 15 kg/m
