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

backgroundIrritable bowel syndrome (IBS) is a chronic, recurring condition, prevalent in the general population. Current medication treatments usually leave patients undertreated. Nowadays, Chinese medicine (CM) is being considered as a promising treatment approach for IBS. However, due to methodological limitations, there is no strong evidence to support CM. Although IBS relapses are common, the relapse assessment has always been neglected in CM study designs. Meanwhile, in clinical practice and studies, it has been found that certain CM formulas can only benefit certain kinds of patients. Discovering what population and illness characteristics likely respond to outcomes may help improve the effectiveness of CM. The aims of this study are to evaluate the efficacy and safety of Tiao-Chang Ke-Min (TCKM) granules for IBS, especially in reducing IBS symptoms' relapse, by a high-quality randomized controlled trial and then to optimize the indication of the TCKM granules. METHODS/

designThis is a parallel-group, randomized, double-blind, placebo-controlled trial embedded with outcome predictive factors. Eligible patients with diarrhea-predominant IBS will be randomized into either a TCKM granule group or a placebo group. Patients from both groups will receive health education. The treatment duration is 4 weeks and the follow-up is 12 weeks. The primary outcome is global improvement measured with adequate relief (AR). The second outcome measures include time until relief, time until first relapse, total relapse times, long-term effectiveness, individual symptoms, IBS-Symptom Severity Score (IBS-SSS), IBS-Quality of Life Questionnaire (IBS-QOL), and Hospital Anxiety and Depression Scale (HADS). Predictive factors associated with patient and illness characteristics have been widely collected. These factors will be embedded in this trial for further identification. DISCUSSION: This trial may provide high-quality evidence on the efficacy and safety of TCKM granules for IBS and a more accurate indication. Importantly, this trial will provide a new research method for improving the therapeutic effects of CM for clinicians and researchers. To address IBS relapse assessment, a series of special definitions of relapse incidents has been made for this trial.
