Metoclopramide and Diphenhydramine: A Randomized Controlled Trial of a Treatment for Headache in Pregnancy when Acetaminophen Alone Is Ineffective (MAD Headache Study).
Trial report in American journal of perinatology, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
objectiveWe investigated whether metoclopramide administered with diphenhydramine (MAD) relieves headache in pregnant women when acetaminophen alone is ineffective, using codeine for comparison. STUDY
designNormotensive pregnant women in the second or third trimester were randomized to MAD intravenously (10 mg and 25 mg, respectively) or codeine orally (30 mg) for headache after 650 to 1,000 mg of acetaminophen failed to relieve their headaches. Headache severity (pain score 0-10) was noted at intervals over 24 hours. The primary outcome was reduction in pain score 6 hours after medication administration. A sample size calculation of 35 patients per group was based on estimated reduction in headache pain score by at least two points, with an
resultsNo difference was seen in the primary outcome. MAD pain scores were lower at 30 minutes (3 ± 2.8 versus 5.8 ± 2.3,
conclusionMAD effectively relieves headaches in pregnant women when acetaminophen fails.
