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

purposeThe effect of altered subsphincteric gastric volume and pressure after bariatric surgery on laryngopharyngeal reflux (LPR) remains largely unknown. This was a cross-sectional pilot study conducted between January 2018 and January 2019 to identify changes in LPR symptoms and signs in bariatric surgery patients presurgery and postsurgery. MATERIALS AND

methodsThirty-four patients listed for bariatric surgery in a single tertiary referral center were recruited, where 31 (77.4% female, mean age 46.3 ± 8.9 years) fulfilled the eligibility criteria. Of the eligible patients, 54.8% and 45.2% underwent sleeve gastrectomy (SG) and gastric bypass (GB), respectively. LPR symptoms were assessed using the self-reported reflux symptom index (RSI). Video-recorded endolaryngeal signs were scored using the reflux finding score (RFS) by two blinded otolaryngologists. Patients' presurgical and 3-month postsurgical body mass index (BMI), RSI, and RFS were determined. Patients were deemed as having LPR when RSI > 13 or RFS > 7.

resultsThere was a significant correlation between the postsurgical RSI and RFS changes (Pearson's r = 0.474, p = 0.007). Of the 31 patients, 12.9% (RSI) and 6.4% (RFS) recovered from preexisting LPR, whereas 22.6% (RSI) and 3.2% (RFS) developed new de novo LPR postsurgery. The postsurgical mean RFS change improved significantly in the GB group compared with that of the SG group (p < 0.05).

conclusionLPR is best assessed clinically using a multimodal approach (RSI and RFS). Bariatric surgery may worsen or lead to de novo LPR. Recognizing the LPR outcomes in these patients is paramount for optimal voice, speech, and swallowing functions.
