1 · What the graph read from it

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.

2 · The registry

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

ImportanceA predictive formula for pediatric nasopharyngeal depth (ND) could tailor nasopharyngeal swabbing technique to individual anatomy and reduce the incidence of false negatives.ObjectiveTo provide a formula predicting ND based on surface anatomy measurements in children.Study DesignProspective pilot study.SettingBritish Columbia Children's Hospital Pediatric Otolaryngology Clinic (Canada) between June 2022 to May 2024.ParticipantsChildren receiving flexible nasal endoscopy at a tertiary otolaryngology clinic.Intervention and Main Outcome MeasuresPredictor variables collected were sex, age, height, weight, curved nasal ala-tragus distance, finger lengths, and history of adenoidectomy. The outcome variable of ND was measured from the nasal nares to the posterior nasopharyngeal wall during routine nasal endoscopy. Relationships between predictor and outcome variables were analyzed. A predictive formula for ND was generated using stepwise linear regression, formula simplification, and model validation.ResultsSixty-three pediatric patients were included (67% male, average age 6.4 years, range 3 weeks-18 years). ND differed by age: average ND for age <2 was 5.4 ± 0.8 cm, ages 2 to 10 was 7.4 ± 1.1 cm, and ages >10 was 9 ± 1.1 cm. Stepwise linear regression resulted in the formula: ND (cm) = ⅔ (pinky length) + ⅓ (ala-tragus distance) + 1 (if history of adenoidectomy) + 1.
