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

aimTo determine the systematic error ( MATERIALS AND

methodsA retrospective offline review was done for patients who underwent IMRT for NPC from June 2015 to May 2016 at our institution. Alternate day kV images were matched with digitally reconstructed radiographs to know the setup errors. All radiographs were matched at three levels - the clivus, third cervical (C3) and sixth cervical (C6) vertebra. The shifts in positions along the vertical, longitudinal and lateral axes were noted and the

resultsTwenty patients and 300 pairs of orthogonal portal films were reviewed. The

conclusionA differential margin along different levels of target may be necessary to adequately cover the target.
