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

introductionCalculating detection rates using data from colonoscopies for all indications, rather than screening examinations, is simpler and can mitigate gaming by endoscopists. We hypothesized that calculating sessile serrated lesion detection rates (SSLDR-A) using all examinations may also be a quality metric for predicting postcolonoscopy colorectal cancer (PCCRC) risk.

methodsThe cohort included New Hampshire Colonoscopy Registry 115,762 patients with an index colonoscopy. The primary outcome was PCCRC, defined as colorectal cancer (CRC) diagnosed ≥6 months after the index colonoscopy. The exposure variables were endoscopist-specific SSLDR-A (using all examinations) and SSLDR-S (using screening examinations), stratified into quintiles. Cox regression was used to model the hazard of PCCRC on SSLDR, adjusting for relevant covariates, such as patient age and sex.

resultsThere were 177 PCCRCs diagnosed in 115,762 patients with index colonoscopies. Higher SSLDR-A and SSLDR-S rates were associated with lower PCCRC risks. After adjusting for covariates, we observed that higher SSLDR-A rates were associated with lower hazard ratios (HRs) as compared with the reference group (SSLDR-A: <1.5%; HR = 1.0 vs SSLDR-A: 1.5% to <3.0%; HR = 0.53, 95% CI 0.35-0.79; SSLDR-A: 3.0% to <5.0%; HR = 0.59, 95% CI 0.38-0.92; SSLDR: 5.0% to <8.0%; HR = 0.44, 95% CI 0.28-0.70; and SSLDR: 8.0+%; HR = 0.20, 95% CI 0.08-0.46). The highest quintile of SSLDR-A (8.0%+) (HR = 0.20, 95% CI 0.08-0.46) and SSLDR-S (8.0%+) (HR = 0.20, 95% CI 0.09-0.44) provided similar protection from PCCRC. DISCUSSION: These findings demonstrate that colonoscopies performed by endoscopists with higher SSLDR-A are associated with a lower risk of PCCRC, validating SSLDR-A as a quality metric. Furthermore, our data suggest that endoscopists should aim for an SSLDR-A of 6% and have an aspirational SSLDR-A of 8.0% or higher.
