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

Globally, the highest cervical cancer mortality rates are found in East Africa. Visual inspection with acetic acid (VIA)-based screening in resource-poor settings has been shown to decrease the proportion of women presenting with late-stage cervical cancer, a process known as clinical downstaging. The only cancer treatment center in Tanzania, Ocean Road Cancer Institute (ORCI) in Dar es Salaam, opened a VIA-based cervical cancer screening program in 2002. We reviewed 6,676 medical records of cervical cancer patients at the ORCI from 2002-2011 to 2014-2018 for stage at diagnosis and screening status, among other variables. We investigated whether clinical downstaging occurred in this period among women screened at the ORCI, when compared to unscreened women. Our results indicated that the proportion of women presenting with late-stage cervical cancer among women screened at the ORCI decreased by 27.7% over the 16-year period (χ
