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

To analyze the predictive value of salivary pepsin for treatment outcomes in laryngopharyngeal reflux (LPR) using multivariate analysis that includes various associated factors. This prospective cohort study was conducted between August 2020 and August 2022. Patients with LPR who had symptoms lasting more than 1 month and a reflux symptom index (RSI) of 14 or higher were enrolled. The participants received a 2-month regimen of proton pump inhibitors (PPIs) treatment and lifestyle modification. Salivary pepsin was checked using fasting saliva before treatment. Salivary pepsin was detected more frequently in the good treatment response group (61.1%), compared to 14.3% in the poor response group. Similarly, patients with higher compliance to lifestyle modifications (> 90%) had a higher chance of a good response (91.7%) compared to those with lower compliance, who had a 53.8% chance of a good response. Other clinical factors have no significant association with treatment response. In multivariate analysis, both pretreatment salivary pepsin and higher compliance with lifestyle modification were found to be independent factors for treatment response (OR 14.457, CI 1.075 ~ 194.37 for both). This study found that positive salivary pepsin and strict lifestyle modification are independent predictors of treatment outcomes in LPR.
