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

objectiveThe objectives of this study were to evaluate the rates of recurrence, survival and pregnancy, and characterize pregnancy outcomes of early-stage cervical cancer(eCC) treated with fertility-sparing methods such as cervical conization (CON) and radical trachelectomy(RT) with or without pelvic lymphadenectomy. STUDY

designThis was a meta-analysis of observational studies analyzed by a random-effects model and a meta-regression to assess heterogeneity.

resultsSixty observational studies encompassing 2,854 patients were included; 17 of which evaluated CON and 43 RT. Three hundred and seventy-five patients were included in the CON group: 176(46.9%) stage IA1 and 167(44.5%) stage IB1. In the RT group, 2479 cases were included: 143(6.0%) stage IA1, 299(12.1%) stage IA2, 1987(79.9%) stage IB1. CON was performed in 347(92.5%) cases, resulting in a recurrence rate of 0.4%(95%CI: 0.0%-1.4%), a death rate of 0%(0%-0%), a pregnancy rate of 36.1%(26.4%-46.2%), a spontaneous abortion rate of 14.8%(9.3%-21.2%) and a preterm delivery rate of 6.8%(1.5%-15.5%). For the RT group, 2273(91.7%) underwent successful surgeries with a recurrence rate of 2.3%(1.3%-3.4%),a death rate of 0.7%(0.3%-1.1%), a pregnancy rate of 20.5%(16.8%-24.5%), a spontaneous abortion rate of 24.0%(18.8%-29.6%) and a preterm delivery rate of 26.6%(19.6%-34.2%). From a subgroup analysis, the recurrence rates for stage IA tumors treated with CON and RT were 0.4%(0.0%-1.9%) and 0.7%(0.0%-2.3%), respectively; and for stage IB were 0.6%(0.0%-2.7%) and 2.3%(0.9%-4.1%).

conclusionFertility-sparing treatment including CON or RT for eCC is feasible and carefully selected women can preserve fertility and achieve pregnancy resulting in live births. CON seems to result in better pregnancy outcomes than RT with similar rates of recurrence and mortality.
