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

introductionGut microbiota plays an important role in tic disorders (TDs); however, clinical research on probiotics for chronic TDs treatment is lacking. We aimed to investigate the effectiveness of probiotics, hypothesizing that their clinical efficacy is comparable to that of clonidine in treating chronic TDs.

methodsPatients were randomly assigned to receive either Limosilactobacillus reuteri or clonidine transdermal patch treatment for 8 weeks while maintaining their existing treatment. The Yale Global Tic Severity Scale (YGTSS); Swanson, Nolan, and Pelham-IV Scale (SNAP-IV); and Child Behavior Check List (CBCL) scores were assessed before and after treatment.

resultsWe matched the patients in both groups for age, sex, age at onset, and tic type. A significant improvement in YGTSS scores was observed in both groups (p = 0.024). The improvement in attention deficits on the SNAP-IV scale was similar between the two groups, with no significant difference (p = 0.465). For hyperactivity disorder, after matching patients in both groups for age, sex, age at onset, tic type, and Children's Yale-Brown Obsessive Compulsive Scale (CY-BOCS) scores, a significant difference in improvement was observed between the groups (p = 0.010), with the probiotics group showing greater improvement (0.3 ± 0.58 vs. 0.1 ± 0.50). At 9 weeks, social ability on the CBCL scale increased by 3.2 ± 6.26 from baseline in the probiotics group and by 0.6 ± 4.07 in the clonidine group, with a significant difference between the two (p = 0.049). Although there was no significant difference in behavioral problems between the two groups (p = 0.347), the trend of improvement was more pronounced in the probiotics group than in the clonidine group (12.7 ± 25.86 vs. 8.4 ± 13.15).

conclusionThe mid-term efficacy evaluation demonstrated that L. reuteri, when added to the treatment of children with chronic TDs, was more effective in improving tic symptoms than clonidine transdermal patch treatment. Additionally, it provided moderate improvement in hyperactivity symptoms.
