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

Background: This single-center pilot randomized clinical study compared the efficacy of biweekly and triweekly 1.41% hydrogen peroxide (H Methods: Eight dental chair units (DCUs) were randomized to Group A (triweekly shock treatment, Results: Group B maintained a 100% compliance rate (≤ 100 CFU/mL) throughout the 6-week period, whereas Group A showed a significantly lower compliance rate of 78.47%, with recurrent microbial rebound during the third week of each cycle. Biweekly shock treatment increased the probability of compliance by 21.53 percentage points compared with triweekly treatment (95% CI: 13.74-29.32, Wald Conclusions: Within the limitations of this single-center pilot study, continuous disinfection with 0.0141% H
