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

backgroundThe use of progestogens for maintenance tocolysis remains controversial, with randomized controlled trials having conflicting results on their efficacy.

objectivesTo evaluate the use of progestational agents for maintenance tocolysis after preterm labor in a systematic review of randomized controlled trials. SEARCH STRATEGY: Electronic databases were searched for reports published before December 2014. Keywords included "tocolysis," "progesterone," "preterm labor," "17-alpha-hydroxyprogesterone," and "vaginal progesterone." SELECTION CRITERIA: Only randomized controlled trials involving progestational agents for maintenance tocolysis were included. DATA COLLECTION AND ANALYSIS: Outcomes were analyzed on an intent-to-treat basis and meta-analysis was performed where appropriate. Relative risks and mean differences with 95% confidence intervals were calculated. MAIN

resultsFour studies (362 women) were included. There were no significant differences between progestational agents and placebo/no treatment in terms of delivery before 34weeks or before 37weeks of pregnancy, time from randomization to delivery, and respiratory distress syndrome. Progestogens were associated with an increase in the neonatal birth weight (mean difference 203.32g, 95% confidence interval 110.85-295.80; P=0.032).

conclusionsThe current evidence does not support the routine use of progestational agents for maintenance tocolysis after an episode of preterm labor.
