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

In a multicenter comparison of PCR assays utilizing 120 quantitated samples of 16 Chlamydia pneumoniae isolates, an LCx research-use-only (RUO) PCR developed by Abbott Laboratories demonstrated 100% sensitivity on 48 samples with >1 copy of DNA per microl of specimen. The sensitivities of five in-house PCR assays ranged from 54 to 94% for the same samples. All six assays showed decreased sensitivities as the DNA copy numbers of the samples decreased. Overall, sensitivities ranged from 68% for the LCx PCR assay to 29% for one of the in-house tests. The LCx RUO PCR and three of the five in-house PCR tests reported no false positives with the 24 negative samples. Increasing the number of replicates tested increased the sensitivities of all of the assays, including the LCx PCR. The LCx RUO assay showed high reproducibility for a single technologist and between technologists, with a kappa agreement of 0.77. The within-center agreements of the five in-house PCR tests varied from 0.19 to 0.74 on two challenges of 60 specimens 1 month apart. The LCx C. pneumoniae RUO PCR shows excellent potential for use in clinical studies, which could enable standardization of results in the field.
