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

designThis was a randomised controlled trial (RCT).

interventionParticipants were assigned randomly to receive periodontal treatment either before 23 weeks' gestational age or after delivery. Treatment consisted of up to four sessions of supragingival and subgingival scaling and root planing using hand and ultrasonic instruments to complete the baseline therapy. Local anaesthesia was used as needed. Those in the treatment group also received full-mouth tooth polishing and oral hygiene home instructions. There were no followup periodontal treatment visits. After delivery, those in the delayed-treatment group received periodontal therapy at no cost. OUTCOME MEASURE: The principal outcome (gestational age <37 weeks) included induced or spontaneous deliveries, foetal demise and miscarriage, but not therapeutic abortions. Secondary outcomes included gestational age <35 weeks; mean birth weight among neonates adjusted for race, sex and gestational age; and a composite measure of neonatal morbidity and mortality before discharge.

resultsThe trial randomised 1806 patients at three performance sites and 1760 evaluable patients completed the study. At baseline, there were no differences between the treatment and control arms for any of the periodontal or obstetric measures. The rate of preterm delivery for the treatment group was 13.1%, and 11.5% for the control group (P 0.316). There were no significant differences when comparing women in the treatment group with those in the control group with regard to the adverse event rate or the major obstetric and neonatal outcomes.

conclusionsPeriodontal therapy did not reduce the incidence of preterm delivery.
