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
introductionMutations at the codon 6 of the beta-globin gene (hemoglobin [Hb] S and HbC) can be routinely identified by various methods and prenatal diagnosis has been available to affected families for several years. However, the presence of maternal cells in fetal samples constitutes a serious potential source of prenatal misdiagnosis and most methods currently used to detect maternal contamination are based on the analysis of highly polymorphic loci. In addition, these methods are labor intensive and time consuming and risk carry-over contamination.
methodWe describe here a one-step method for mutation detection that uses fluorescent hybridization probes with melting curve analysis for both simultaneously prenatal diagnosis of sickle cell disease and potential maternal contamination.
resultsRetrospective and prospective prenatal diagnosis studies (conducted in 20 and 50 cases, respectively), using both the regular procedure and real-time PCR assay show perfect concordant results. We show in addition, that as little as 5% maternal contamination can be detected and that genotype determinations are unambiguous.
