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

introductionOn the topic of adjuncts to scaling and root planing (SRP), numerous randomized clinical trials (RCTs) were published by a single group of authors and frequently reported unusually large effect sizes. A meta-analysis in part 1 of this project failed to explain the causes for these unusual findings. We assessed the reporting quality and trial registration discrepancies to examine the possibility of replicating the work of this research group as well as the overall rigor of the research methodology.

methodsThis study was preregistered at the Open Science Framework (https://osf.io/4meyd/). The Scopus platform was utilized for the RCT search on SRP adjuncts in intrabony defects in patients with periodontitis as compared with SRP alone. The search analysis was limited from 2010 to 2017, and RCTs on SRP adjuncts published by a single research group were selected for screening and inclusion. RCT registration records were assessed for consistency.

resultsOut of 92 studies that were retrieved from Scopus and PubMed, 32 were included for quality assessment per the CONSORT guidelines (Consolidated Standards of Reporting Trials). Results showed that all RCTs were characterized by a low reporting quality. The majority of CONSORT items scored <50%, including critical items (randomization, registration, and blinding). When registration records were compared with published RCTs, several discrepancies were found. The per-protocol follow-up duration was compared against the study's initiation and termination dates. Only 38% of the RCTs presented a follow-up period within the initiation and termination dates. The remaining RCTs showed inconsistent follow-up in comparison with the initiation and termination dates.

conclusionRCTs by this group were characterized by poor adherence to reporting quality guidelines. Crucial RCT elements, such as randomization, blinding, and primary outcomes, were not reported properly. RCT registration records revealed systematic inconsistencies when compared with RCT publication. Therefore, the unusually large effects reported by this group should be viewed with extreme caution. KNOWLEDGE TRANSFER STATEMENT: The included randomized clinical trials were characterized by poor adherence to reporting quality guidelines, missing information about important trial items, and discrepancies between the reports and trial registrations. This quality assessment should guide clinical research and show clinicians that they should be cautious when applying evidence in their clinical practice.
