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

Late Chlamydia trachomatis inclusions express each member of the surface-exposed polymorphic membrane protein family (Pmp subtypes A through I) with a reproducible distribution of fully-on, fully-off and intermediate phenotypes. This observation is consistent with observed variable Pmp antibody profiles in C. trachomatis-infected patients and has led to the hypothesis that the pmp gene family forms the basis of a phase variation-like mechanism of antigenic variation. Here we investigate and compare the developmental expression of each of the nine pmp genes under conditions of optimal in vitro growth with that under conditions that promote prolonged survival of chlamydiae when exposed to penicillin-induced stress. We demonstrate that the pmp gene family includes distinct transcriptional units that are differentially expressed along development and differentially responsive to stress. In particular, our results indicate that expression of pmpA, pmpD and pmpI is uniquely unaffected by stress, suggesting that the PmpA, PmpD and PmpI proteins play a critical role in the pathogenesis of C. trachomatis.
