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

BACKGROUND/

aimsEndoscopic retrograde cholangiopancreatography (ERCP) is a technically challenging procedure rarely associated with severe postprocedure complications. Hormonal changes during pregnancy promote cholelithiasis, but there are limited clinical data available on the outcomes of ERCP in pregnant women. ERCP techniques without irradiation were recently introduced as potential alternative. We performed a systematic review and meta-analysis to assess the safety of ERCP in pregnancy and to compare outcomes of radiation versus nonradiation ERCP. MATERIALS AND

methodsA systematic search of PubMed, Medline/Ovid, Web of Science, and Google Scholar through April 18

resultsIn all, 27 studies reporting on 1,307 pregnant patients who underwent ERCP were identified. Median age was 27.1 years. All results were statistically significant (P < 0.01). The pooled event rate for overall adverse outcomes was 15.9% (95% CI = 0.132-0.191) in all studies combined, 17.6% (95% CI = 0.109-0.272) in nonradiation ERCP (NR-ERCP) subgroup and 21.6% (95% CI = 0.154-0.294) in radiation ERCP subgroup. There was no significant difference in the pooled event rate for fetal adverse outcomes in NR-ERCP 6.2% (95% CI = 0.027-0.137) versus 5.2% (95% CI = 0.026-0.101) in radiation ERCP group. There was no significant difference in maternal pregnancy-related adverse outcome event rate between NR-ERCP (8.4%) (95% CI = 0.038-0.173) and radiation ERCP (7.1%) (95% CI = 0.039-0.125). Maternal nonpregnancy-related adverse outcome event rate in NR-ERCP was 7.6% (95% CI = 0.038-0.145), which was half the event rate in radiation ERCP group of 14.9% (95% CI = 0.102-0.211).

conclusionsERCP done by experienced endoscopists is a safe procedure during pregnancy. Radiation-free techniques appear to reduce the rates of nonpregnancy-related complications, but not of fetal and pregnancy-related complications.
