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.
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
objectiveTo determine if implementation of a tiered clonidine dosing protocol reduces the incidence of withdrawal compared with the preintervention phase.
methodsThis is a pre- and postinterventional cohort study in which preintervention data were collected for 6 months for baseline incidence of dexmedetomidine withdrawal and institutional practice of clonidine use. This was followed by implementation of an enteral clonidine dosing protocol based on the length of dexmedetomidine infusion and continued data collection for an additional 6 months. Patients were enrolled in both arms after ≥72 hours on dexmedetomidine. Withdrawal was described as tachycardia or hypertension and elevated Withdrawal Assessment Tool-1 or study questionnaire scores.
resultsThe preintervention phase had 49 patients included in analysis and the intervention phase had 30 patients. Incidence of withdrawal in the overall preintervention vs intervention cohorts was not significantly different, but in patients who received clonidine there was a trend towards less withdrawal in the intervention vs preintervention cohort (36% vs 52%). The hours on dexmedetomidine nor cumulative dexmedetomidine dose differed between the cohorts (161.5 vs 152.8 hours, p = 0.49; 126.34 vs 134.76 mcg/kg, p = 0.54). With implementation of the protocol, more patients were weaned off dexmedetomidine within 24 hours (67% vs 39%, p = 0.06).
conclusionsTo the authors' knowledge, this is the first prospective study assessing the use of an enteral clonidine dosing protocol to prevent dexmedetomidine withdrawal in children. With implementation of the protocol a trend towards reduction in withdrawal in the intervention cohort was documented despite faster weaning time with similar dexmedetomidine exposure.
