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

This study compares rates of trial of labor after Cesarean delivery (TOLAC) and rates of successful TOLAC between 1990 and 2009. Serial cross-sectional analyses were performed using the National Hospital Discharge Survey data to compare rates of TOLAC and TOLAC success between 1990 and 2009. Joinpoint regression was used to assess trends over time, and logistic regression with marginal effects was used to examine the unadjusted and adjusted significance and magnitude of trends. The rate of TOLAC reached a high of 51.8 % (95 % CI 47.8-55.8 %) in 1995 and a low of 15.9 % (95 % CI 13.8-18.0 %) in 2006, declined, on average, 4.2 (95 % CI -4.8 to -3.9) percentage points per year between 1996 and 2005. Rates increased significantly from 1990 to 1996 and 2005 to 2009. TOLAC success was at its highest rate in 2000, 69.8 % (95 % CI 65.2-74.3 %) and its lowest in 2008, 38.5 % (95 % CI 28.1-48.8 %). The rate of TOLAC success increased significantly between 1990 and 2000, but declined thereafter an average of 3.4 % points per year (95 % CI -4.3 to -2.5). The rate of TOLAC in the US decreased between 1996 and 2005 and the rate of successful TOLAC has declined from 2000 to 2009.
