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.

Abstract

objectiveTo determine whether IV metoclopramide 20 mg + diphenhydramine 25 mg (M + D) was more efficacious than IV placebo for acute moderate or severe posttraumatic headache in the emergency room.

methodsWe conducted this randomized, double-blind, placebo-controlled, parallel-group study in 2 urban emergency departments (EDs). Participants who experienced head trauma and presented to our EDs within 10 days with a headache fulfilling criteria for acute posttraumatic headache were included. We randomized participants in a 1:1 ratio to M + D or placebo. Participants, caregivers, and outcome assessors were blinded to assignment. The primary outcome was improvement in pain on a scale of 0 to 10 between baseline and 1 hour after treatment.

resultsThis study was completed between August 2017 and March 2020. We screened 414 patients for participation and randomized 160: 81 to M + D and 79 to placebo. Baseline characteristics were comparable between the groups. All enrolled participants provided primary outcome data. Patients receiving placebo reported mean improvement of 3.8 (SD 2.6), while those receiving M + D improved by 5.2 (SD 2.3), for a difference favoring metoclopramide of 1.4 (95% confidence interval [CI] 0.7-2.2,

conclusionM + D was more efficacious than placebo with regard to relief of posttraumatic headache in the ED. TRIAL REGISTRATION INFORMATION: ClinicalTrials.gov Identifier: NCT03220958. CLASSIFICATION OF EVIDENCE: This study provides Class I evidence that for patients with acute moderate or severe posttraumatic headache, IV M + D significantly improved pain compared to placebo.
