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 recent years, highly sensitive assays have been developed that detect HIV-1 drug resistance mutations when present at less than 1% of the viral population. These assays are powerful tools when attempting to determine the clinical implications of these low level resistant virions after the administration of single-dose nevirapine. This report demonstrates that non-drug resistant polymorphisms in the primer-binding site for the allele-specific PCR (ASPCR) assay impact primer binding resulting in significant discrepancies in the assay's performance. Specifically, the use of a "universal" set of ASPCR primers caused an overestimation of the K103N (ntAAC) mutation at position 103 of reverse transcriptase when primer binding site polymorphisms resided close to the 3' end of the allele-specific primer. Drug resistance was predicted at values ranging from 0.69% to 7.69% for a sample containing only 1% resistance mutations and 3.35-31.84% for a sample containing 5% mutations. Conversely, the use of polymorphism-specific primers detected 1.15-1.36% and 5.20-5.71% resistance for the same 1% and 5% samples. The results demonstrate the need to account for sequence polymorphisms when designing and implementing this highly specific assay.
