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

objectivesThe top 10 research priorities (RPs) for Barrett's oesophagus (BO) were published in 2017. This study aimed to identify the current research landscape on addressing RPs.

designSystematic mapping review. DATA SOURCES: ClinicalTrials.gov, EU Clinical Trials Register and ISRCTN registry. ELIGIBILITY CRITERIA: Adult (>18 years) interventional studies registered in those three registers from 31 August 2017 to 1 July 2024 and addressing any of the top 10 RPs were eligible. DATA EXTRACTION AND SYNTHESIS: Two researchers extracted data using prespecified tables, from the three registers and pooled them together.

resultsWe identified clinical trials (n=735) registered in the last 7 years (ClinicalTrials.gov (611), EU Clinical Trials (63), ISRCTN (61)), and 244 were included as they addressed RPs, after removing 14 duplicates. Most studies (168/244, 69%) addressed RP8 (searching alternative treatments for reflux), including medicinal products (86/168 (51%)), surgical methods (29/168 (17%)) and endoscopic methods (26/168 (15%)). There were 41/244 (17%) trials registered aiming investigations for screening and surveillance of BO in a primary care setting (RP3). 92% of studies were distributed among RP8, RP3 and RP5. The remaining RPs (RP1, RP2, EP4, RP6, RP7 and RP9) had only 8% of 244 studies, while the RP10 had none.

conclusionA higher concentration of studies on RP8, RP3 and RP5 may demonstrate the high clinical and global commercial demand on them, while the scarcity of trials for RP1, RP2, RP4, RP6, RP7, RP9 and RP10 unveils gaps in research meeting priorities. This unequal distribution of the trial landscape raises the question: do we correctly address the RPs?
