Doxapram versus methylxanthine for apnea in preterm infants.
Synthesis in The Cochrane database of systematic reviews, 2000. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers, 1 of them a synthesis that pooled 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.
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
backgroundRecurrent apnea is common in preterm infants, particularly at very early gestational ages. These episodes of loss of effective breathing can lead to hypoxemia and bradycardia which may be severe enough to require resuscitation including use of positive pressure ventilation. Doxapram and methylxanthine drugs have been used to stimulate breathing and so prevent apnea and its consequences.
objectivesTo assess the effects of doxapram compared with methylxanthine in preterm infants with recurrent apnea. SEARCH STRATEGY: The Cochrane Collaboration Clinical Trials Register (Cochrane Library issue 3, 2000), MEDLINE (1966- July 2000), reference lists of relevant articles and conference proceedings. SELECTION CRITERIA: Randomized and quasi-randomized trials of doxapram compared with methylxanthine (e.g. theophylline, aminophylline or caffeine) for the treatment of apnea in preterm infants. DATA COLLECTION AND ANALYSIS: The methodological quality of each trial was reviewed by the second reviewer blinded to trial authors and institution(s). Additional information was requested from authors. Each reviewer extracted the data separately, then they were compared and differences resolved. Meta-analysis was carried out with use of relative risk and risk difference. MAIN
resultsThree trials involving 56 infants were included. No difference was detected between intravenous doxapram or methylxanthine in the incidence of failed treatment within 48 hours (relative risk 1.16, 95% confidence interval 0.43 to 3.13). No infants were reported to have been given mechanical ventilation on either treatment. No adverse effects were reported. REVIEWER'S
conclusionsIntravenous doxapram and intravenous methylxanthine appear to be similar in their short term effects for treating apnea in preterm infants, although these trials are too small to exclude an important difference between the two treatments or to exclude the possibility of less common adverse effects. Longer term outcome of infants treated in these trials has not been reported. Further studies would require a large number of infants to clarify whether there might be differences in responses or adverse effects with these two drugs at different ages.
